Offensive lineman Tate Nichols and inside linebacker Anthony Rabasa underwent shoulder surgery and will be out for the season, coach Brian Kelly said Wednesday. 

"We didn't want to wait any longer on that shoulder," Kelly said of Tate. "We probably could've continued to get by with a harness but we want him full go for spring ball because he'll be vying for a starting position."

In other news, linebacker Danny Spond has been cleared to play against the Air Force Academy after recovering from a hamstring injury. 

Meanwhile, freshman defensive end Stephon Tuitt apologized for missing a class and therefore not being allowed to make the trip to West Lafayette, Ind., for Saturday night's 38-10  win over Purdue. Tuitt is also expected to play against the Falcons at Notre Dame Stadium on Saturday.

"He apologized to the team for letting them down," Kelly said. "He took full responsibility for his actions. We talked to his mom. They all understand as a family why he's here and that's to get that education."
