Oregon coach Chip Kelly doesn't discuss injuries, but if he did, there would be a lot to talk about.
Oregon lost two of its top seniors for the season this week and a handful of other players are banged up as the Ducks prepare to host Tennessee Tech on Saturday.
All-American senior safety John Boyett missed the Fresno State game and announced on Sunday that he would have season-ending surgery on both knees. Offensive lineman Carson York, who suffered a serious knee injury in the Rose Bowl, returned to play in Oregon's first two games but suffered a broken kneecap against Fresno State and will need season-ending surgery.
Boyett will be replaced by junior Avery Patterson, who made his third career start on Saturday.
York and Boyett were key figures during Oregon's three straight Pac-12 Conference championships as both started 36 games in their career.
--Only two games into the season, Nebraska coaches are contemplating personnel changes on defense.
That's what happens when your opponent was a couple of kneel-downs away from accumulating the most yards ever against a Nebraska defense. As it was, UCLA amassed 653 yards, prompting an early-season evaluation by the NU staff.
"Everybody is in the equation right now," first-year defensive coordinator John Papuchis said. "If we have to work 24 hours a day for the next seven days, and really for the next three months, we're going to figure it out."
---Robert Marve, Purdue's oft-injured quarterback, has a torn ACL, but it might not end his season.
The senior may be able to return later this year, the Lafayette Journal and Courier reported Tuesday.
Marve already has experienced the agony of two previous ACL tears. He missed one season at Miami with the injury before transferring to Purdue and sitting out the 2009 season. In 2010, he played only four games for the Boilermakers before suffering a torn ACL. His recovery also kept him out of the first two games of the 2011 season.
Marve started Purdue's opener against Eastern Kentucky and shared duties last week against Notre Dame with Caleb TerBush, who was suspended for the Boilermakers' first game.
---Kansas linebacker Prinz Kande suffered a season-ending knee injury in his first career start last Saturday.
The redshirt junior came out of the Jayhawks' loss to Rice on Saturday with a torn ACL and MCL, the Lawrence Journal-World reported Tuesday.
Because the injury occurred in the second game of the season, Kande could be eligible for a medical redshirt.
---Wisconsin Wide receiver Jared Abbrederis should be able to play Saturday against Utah State after being knocked out of last week's loss to Oregon State with a concussion.
Badgers coach Bret Bielema said Tuesday that the former walk-on was "slightly concussed" but recovering and apparently will receive clearance for game action.
Abbrederis is Wisconsin's leading receiver in two games with seven receptions and two touchdowns.
---Jordan Wynn, who was Utah's starting quarterback in itsr first two games this season, has announced that he will retire from football after sustaining his fourth shoulder injury in Saturday's game against Utah State.
Wynn was forced out of Saturday's game shortly before halftime when he injured his left shoulder, and he probably will require surgery.
Wynn has had three shoulder operations -- two on his left, one on his right -- since the spring of 2010, and he missed the final nine games last season because of a shoulder injury.
He is a redshirt junior this season, so he could have returned to play next season even if he was sidelined for the remaining of this season, but he decided he's had enough.
