Left tackle Aundrey Walker and middle linebacker Lamar Dawson missed most of practice with unspecified injuries. Walk-on Nathan Guertler filled in for Walker and freshman Scott Starr replaced Dawson.
Kiffin indicated that weakside linebacker Hayes Pullard would move to the middle spot and redshirt freshman Anthony Sarao would step in for Pullard before Starr would replace Dawson in a game situation. He was unclear on the contingency plan at left tackle, saying Guertler would be the backup "as of right now."
Center Khaled Holmes and receiver Robert Woods (ankle) continued to be very limited in practice, and cornerback Brian Baucham continued to sit out. Receivers Victor Blackwell and Farmer both sat out all of practice.
Cornerback Isiah Wiley and linebacker Marquis Simmons are expected to be out another week while they await their summer-school grades and find out about their eligibility for the coming season.
Flournoy ahead of everybody else
With Blackwell and Farmer on the sideline and freshman Nelson Agholor still adjusting to the speed of the game, coach Lane Kiffin said fourth-year junior De'Von Flournoy is "way ahead" of his competition in the race to be the No. 3 receiver behind Woods and Marqise Lee.
"Nelson has worked hard but he's still just trying to learn it," Kiffin said. "Just like spring, Flournoy is doing really well and very consistent."
Wright standing out
Kiffin said junior safety Demetrius Wright has been the best non-starter on the defense through three practices.
"He's made a ton of plays and had a phenomenal attitude and great approach to the game," Kiffin said. "He's a guy going into his third year who seems to have turned the corner."
Wright is competing with senior Jawanza Starling for the opportunity to start at strong safety next to T.J. McDonald.
Ideally, Kiffin said, Wright and Starling would rotate on defense and on special teams this season to keep both players fresh. And even McDonald would do the same thing with Drew McAllister and/or Josh Shaw.
Final notes: Freshmen Max Tuerk and Leonard Williams earned praise from coach Lane Kiffin for their play thus far in camp. Kiffin said Tuerk has made "very few mental mistakes." ... Freshmen cornerbacks Kevon Seymour and Devian Shelton, who have run some with the second-team defense, were also credited by Kiffin. ... Players had indicated earlier this week that practices would be shorter this camp than in past years, but Wednesday's session checked in at roughly three hours long. ... The Trojans will scrimmage at the Coliseum on Friday afternoon. Kiffin said he was unsure whether or not they would tackle during it.
