Jarrett Could Be Out 2-4 Weeks

All-American split end Dwayne Jarrett is doubtful to play against Washington State and could sit out two to four weeks because of a shoulder injury suffered against Arizona, USC Coach Pete Carroll said Sunday.

“It depends on how he responds in the next few days,” Carroll said. “Knowing what kind of competitor he is, I wouldn’t be surprised if he’s moving around and trying to go.”

Jarrett sprained his left shoulder after making a diving attempt to catch a pass during the Trojans’ 20-3 victory at Tucson on Saturday. The 6-foot-5 junior stayed in the game, and in the third quarter tied the Pacific 10 Conference career record with his 32nd touchdown reception, which gave the Trojans a 10-0 lead. Jarrett was taken to the locker room shortly afterward and did not return to the game.

X-rays Sunday revealed no further damage, Carroll said.

Sophomore Patrick Turner, senior Chris McFoy and freshman Vidal Hazelton are expected to step up in Jarrett’s absence, Carroll said.

With Stanley Havili out for possibly six weeks because of a broken leg, senior Mike Brittingham is on track to start at fullback on Saturday at Washington State.

Fourth-year junior Jody Adewale will back up Brittingham.

After senior Ryan Powdrell suffered a season-ending injury against Nebraska, Luthur Brown practiced a little more than a day at fullback but returned to defense. Carroll said Brown’s status and other possible moves would be discussed among coaches today.

“We might not know anything till Tuesday,” he said.

Early last week, freshman Allen Bradford was quoted in a published report as saying he would not move from tailback to fullback.

Bradford had been switched from safety to tailback during training camp.

Carroll said Sunday that coaches had not discussed a move to fullback with Bradford or freshman tailback Stafon Johnson.

Late last week, Bradford said, “I just don’t see myself there, playing fullback.” He also said he was unaware that Heisman Trophy winner Marcus Allen went through several position switches before he became USC’s primary ballcarrier in the early 1980s.

Allen arrived at USC after playing quarterback and defensive back in high school in San Diego. He moved to tailback as a freshman in 1978, but Coach John Robinson switched him to fullback in 1979.

Allen blocked for Heisman Trophy winner Charles White, rushed for 649 yards and caught 22 passes for 314 yards during his sophomore year. In 1980 he returned to tailback. The next year he won the Heisman.

When informed of Allen’s career path at USC, Bradford said, “That’s crazy. I had no clue about that.”

USC’s experience with instant replay during the victory over Arizona, and the delay it caused, did nothing to make Carroll a fan of the system.

Replay officials disallowed two receptions by flanker Steve Smith, including an apparent touchdown, after review. An Arizona receiver who was initially ruled out of bounds while making a catch was credited with a reception after review.

“It really is disruptive to the game,” Carroll said.

USC remained third in the Associated Press media poll, second in the coaches’ poll and was ranked second in the first Harris Interactive poll.... Arizona’s 44 plays were the fewest against USC since Pittsburgh had 34 in 1974, according to a USC athletic department spokesman.
