"A bunch of guys returned to the practice field," he said. "I don't know if you could tell, but it was like a busload of guys came in today! It was kinda' fun and it feels different -- the energy about it. Those guys were all excited to get back out ... that should help us keep the week competitive."

Here's who practiced after being injured and/or missing at least part of last week's practice:

• Jordon Cameron
• Butch Lewis
• Zack Heberer
• Jimmy Miller
• Joe McKnight
• Vidal Hazelton
• Everson Griffen
• Brian Cushing
• Kaluka Maiava
• Chris Pousson

After listing out all the names, Carroll mused, "It feels like there are some more guys popping out!"

No word on when Gerald Washington will be back (he was out with an ankle injury).

Regarding Joe McKnight’s case, which had him in a boot Monday, USC coach Pete Carroll said: “This is a hard one to tell. Obviously this is a real critical and painful injury for a running back particularly, but it’s hard on everybody.”

With Stafon Johnson (illness) and Allen Bradford (hip) also missing practice, redshirt freshman Broderick Green moved up to the No. 2 tailback spot behind C.J. Gable.

The headline injury in training camp was a dislocated kneecap suffered two weeks ago by starting quarterback Mark Sanchez. After seeing him throw in 1-on-1 and 7-on-7 drills, Carroll was pleased with Sanchez's progress and said that he could be practicing at full speed in the next couple of days. That would allow Sanchez, who watched the mock game from the sideline, to participate in game-week preparations.

Asked about his other quarterbacks, Mitch Mustain and Aaron Corp, Carroll wasn't saying much without watching the film. "There were no major breakdowns in communication ... we made it through, I think this was just another day for those guys growing."

Sophomore tailback Joe McKnight appeared fine despite dealing with a series of random and presumably painful injuries over the last couple of weeks.

There was some concern over how sharp USC looked on the lines, with a few penalties and turnovers sprinkled in. More coverage after the jump.

WHITE TEAM DEFEATS CARDINAL TEAM, 28-7, IN USC FOOTBALL INTRASQUAD SCRIMMAGE

        LOS ANGELES–The White team, comprised mainly of first and second teamers, defeated the Cardinal (reserves) team, 28-7, in the USC football team’s final intrasquad scrimmage of fall camp in front of 8,000 fans in the Coliseum on Thursday (Aug. 21).
         The White team scored a touchdown in each quarter.  After defensive end Kyle Moore deflected a first quarter pass by Cardinal team quarterback Garrett Green, fellow end Everson Griffen intercepted it in the end zone for a score.  But the Cardinal team responded on its following possession, capping a 74-yard drive with Green’s 12-yard TD pass to wide receiver Brice Butler. 
        Late in the first half, tailback Joe McKnight scored on a 6-yard run that culminated a 69-yard drive for the White squad.
        The White team scored on its first possession of the second half on an 88-yard drive.  Quarterback Aaron Corp hit tight end Blake Ayles on a 12-yard pass, but Ayles fumbled the ball into the end zone and offensive guard Zack Heberer fell on it for a touchdown.
        Quarterback Mitch Mustain hit fullback Adam Goodman for a 2-yard TD on the White team’s final possession of the game to finish the scoring.
        Corp (8-of-10 passing for 85 yards) and Mustain (10-of-14 for 92 yards) split time in the scrimmage.  Mark Sanchez, who entered fall camp as the starting quarterback before dislocating his kneecap on Aug. 8, participated in pre-game drills and could return to practice fulltime next week.
        McKnight ran for 32 yards on 3 carries and had 34 more yards on 3 punt returns.  Tailback Allen Bradford added 39 yards on 6 rushes. Wide receiver Vidal Hazelton had 5 receptions for 44 yards, while Ayles had 3 for 55 yards.
        For the Cardinal team, Green was 10-of-19 passing for 134 yards, but was intercepted twice.  Wide receivers Jordan Cameron (81 yards), D.J. Shoemate (36 yards) and Butler (19 yards) each had 3 catches. Shoemate added 63 yards on 3 kickoff returns.
        The Cardinal defense was led by safety Drew McAllister’s 8 tackles and linebacker Jordan Campbell’s 5 stops.
        Garratt topped the White squad with 3 tackles, while safety Taylor Mays had 3 deflections.
        Six-time defending Pac-10 champion USC opens its season on Aug. 30 at Virginia.

2008 CFN Unit Rankings

Defenses

1. USC
When linebackers Rey Maualuga and Brian Cushing decided to forego the NFL Draft for one more year, it ensured that the Trojans would have one of the nastiest back sevens in the country.  Not only are the two seniors All-America-caliber, but the secondary is sensational. Safeties Kevin Ellison and Taylor Mays are among six players with starting experience.  Even without current pros Sedrick Ellis and Lawrence Jackson, the defensive line will be just fine. On the outside, speedy Everson Griffen is good enough to make folks forget about Jackson. On the inside, senior Fili Moala is about to shed his anonymity while making a strong push for All-American honors and a spot in the first round of next year’s NFL Draft.    

Offenses

10. USC
Mark or Mitch? The battle between Mark Sanchez and Mitch Mustain to replace John David Booty at quarterback isn’t exactly over. Sanchez got the nod in April, but he got hurt and is questionable for the start of the season. Mustain has done nothing but impress the staff since transferring from Arkansas. Whoever gets the ball will have gobs of speed and explosiveness surrounding him. After getting a taste of action as a freshman, RB Joe McKnight is on the tarmac and preparing for national lift-off. The receivers are a year older, with the size, athleticism, and addition of former Hog Damian Williams to dominate opposing secondaries. The line loses four starters, putting the onus on sophomores Kristofer O’Dowd, Butch Lewis, and Zack Heberer to perform like vets.         

Defensive Backs

2. USC
SC has had the Pac-10’s best pass defense two years running. There’s more than enough returning talent and former prep All-Americans to run that streak to three, although a few more interceptions would be nice. In Kevin Ellison and Taylor Mays, USC is home to a couple of hard-hitting enforcers with All-America potential. If Josh Pinkard is even close to where he was a couple of years ago, no program in the country will be able to match them at the position. Sure to get picked on early, Shareece Wright needs to give opposing quarterbacks a reason to not look to his side.

Defensive Lines

3. USC
Sedrick Ellis and Lawrence Jackson were two of the first 28 picks in April’s draft, yet the Trojans are going to be more than fine up front. Fili Moala and Everson Griffen are the new headliners of a front wall that’ll rely on a deeper group of players this fall. The Trojans are so quick and strong up front, opposing backs are rarely able to get to the second level. Of course, not that things get any easier there. Moala is going to make himself plenty of money this fall, and Griffen and Kyle Moore are big enough on the outside to be valuable assets in run support.

Linebackers

1. USC
Rey Maualuga and Brian Cushing are a pair of NFL-ready linebackers still hanging around the Pac 10. Their presence will help ease the transition of Luthur Brown or Kaluka Maiava into the lineup, while giving the program a couple of intimidating defensive players who opposing coaches will have to account for every Saturday. Led by Maualuga and Cushing, this group has a nose for the football and a gift for fighting through blockers to get to the ball carrier. With the front seven that USC will be rolling out this year, the only tackles the safeties and corners make will be on completed passes.

Running Backs

6. USC
Even after Emmanuel Moody transferred to Florida, there isn’t a school in the nation that features four backs as talented as the ones in this backfield. The Trojans are basically injury-proof, meaning even if one or two players went on the shelf, the running game would survive. As is the case with many USC positions, Pete Carroll will be forced to do a juggling act to be sure that all of his gifted runners are well fed throughout the season.  It’s going to be a challenge.  While Joe McKnight is the star-in-waiting, Stafon Johnson might actually finish the year with the most carries.

Mark Haas put together another fun version of UCS Cribs with David Buehler, Greg Woidneck and Zack Heberer showing off their diggs. If you stay tuned for the outtakes, a 5.4 earthquake hit while they were trying to film the intro.

Make that a thin cardinal line protecting USC's backfield, which also happens to be hamstrung by injuries. While every team looses players during the season (Cal lost to Oregon State without their starting QB, Stanford beat USC without their's), can anybody in the nation match up with the Trojan's carnage?

From USC football's weekly press release:

Already this season, 11 starters or projected starters have missed games with injuries:  S-CB Josh Pinkard (6 games), C Matt Spanos (3 games), TB C.J. Gable (3 games), LB Brian Cushing (3 games), CB Shareece Wright (2 games), OG Chilo Rachal (2 games), C Kristofer O’Dowd (2 games), QB John David Booty (1 game), CB Cary Harris (1 game), WR Patrick Turner (1 game) and TB Chauncey Washington (1 game).

Also, a number of key backups have missed games due to injuries: CB Kevin Thomas (6 games), OG-C Nick Howell (6 games), TB Broderick Green (6 games), TE Jimmy Miller (5 games), LB Chris Galippo (3 games), TB Stafon Johnson (2 games), WR Travon Patterson (2 games), OT Butch Lewis (2 games), OT Charles Brown (1 game), QB Mark Sanchez (1 game), S Will Harris (1 game) and CB Vincent Joseph (1 game).  Pinkard, Gable, Thomas, Howell, Green, Galippo, Patterson have season-ending injuries.

The impact of these injuries has been enormous. The team could be one fractured finger or a healed foot away from a 6-0 record.

Looking ahead to Notre Dame, here's more from the Sports Information Department:

POSSIBLE:  TB Stafon Johnson (foot), OT Sam Baker (hamstring), S Kevin Ellison (nose), OT Charles Brown (ankle), LB Rey Maualuga (hip), OG Zack Heberer (shoulder), QB John David Booty (finger), LB Brian Cushing (ankle), OG Chilo Rachal (knee), CB Shareece Wright (hamstring), C Kristofer O’Dowd (kneecap), TE Jimmy Miller (back).

OUT:  TB C.J. Gable (abdomen), WR Travon Patterson (foot), LB Chris Galippo (back), S-CB Josh Pinkard (knee), OG-C Nick Howell (hernia), TB Broderick Green (foot), CB Kevin Thomas (shoulder), OT Martin Coleman (shoulder), DE Trey Henderson, WR Damian Williams (shoulder).

That ignores all the players who are just dinged up (see Jeff Byers, pictured above) and leaves out two recently announced injuries to Kyle Moore and Terrell Thomas (hamstring).

Here's what John David Booty's hand looked like after practice today. He didn't throw at all, but he's supposed to try tomorrow with a glove.

Hershel Dennis, the most likely starting tailback, injured his hamstring and sat out the practice. Petros Papadakis says while there certainly is new talent for the Trojans to tap into, Hershel Dennis is the only one who can pick up blitzes and understand the offense.

5-star recruit, and now a junior, Whitney Lewis looked good running the ball though.

Ryan Powdrell also saw some action in the backfield along with Brandon Hancock and Joey Adewale.

S Antwine Perez sported a beard and played on the first string defense. We love this guy. Look for him to make an immediate "impact".

The other freshman in attendance, but on the sidelines: RB Stafon Johnson, OL Zack Heberer, DL Alex Parsons, WR Travon Patterson, RB Kenny Ashley and DB Alfred Rowe.
