Michael Lev of the Orange County Register provides an injury update for USC, and it ain't pretty: 12 players who are either projected starters or likely contributors are expected to be out or limited when spring practices start on March 22.
Obviously, as Lev points out, it's premature to panic because sitting out spring is often about being healthy in the fall.
Still, it's quite a list (see link for details): WR Kyle Prater, OL Khaled Holmes, OT Kevin Graf, C Abe Markowitz, DE Wes Horton, DL Armond Armstead, DT Christian Tupou, MLB Devon Kennard, OLB Shane Horton, S Drew McAllister and CBs T.J. Bryant and Torin Harris.
Of particularly concern: Three offensive linemen and eight defenders are out.
The Trojans lack depth on their offensive line, which must replace three starters as well as part-time starter Butch Lewis. Now it appears that left tackle Matt Kalil will be the only full-go returning starter available this spring.
Meanwhile, the defense is looking to bounce back from a sub-par year under coordinator Monte Kiffin. While injuries to veterans will allow younger players to see more action, there's something to be said for the veterans being available to more fully digest the elder Kiffin's schemes during spring when there's more time to teach.
