Storylines from Tuesday practice

* It was a full pads practice Tuesday as the Trojans continue preparations for Notre Dame.

* Torin Harris did not practice. Kyle Prater was ill and did not practice.

* Marc Tyler said he is preparing as if he will be able to play.

* Best defensive play of the day came from Dion Bailey, who tipped a pass away from Xavier Grimble in the end zone.

* George Farmer got stripped on a run play and the coaches used that to remind the players of how important ball security will be in this game.

* Lane Kiffin says the Irish are playing well in all three phases of the game. Of Manti Te'o, he said "He's playing fantastic, I wish he was here."

* More from Kiffin: "They are a few bounces away from being [undefeated]. They are very physical, they come at you straight ahead and knock you back. They have a really good front seven."
