From espn.com through Steve Harris:
News today wasn't great for the D, though. Defensive tackle A'i Ahmu, the Cougars best interior lineman, turned himself in to the WSU Police Department on Wednesday after a warrant for his arrest was issued because he missed a court date on a minor-in-possession of alcohol charge, according to the Seattle Times.
The Seattle Times reports today that Ahmu will miss the second half of Saturday's game, though it wasn't clear which half he would miss. His replacement is senior walk-on Adam Hainline.
WSU Coach Wulff said projected starting wide receiver Jeshua Anderson (hernia surgery) has been ruled out for Saturday along with second-stringers Jason Stripling (an outside linebacker with a sprained toe) and Toby Turpin (a defensive tackle with torn thumb ligaments).
And guard Brian Danaher is probably going to play after sitting out several practices this week due to an injured butt, er, strained glute. See? It's tough to play in Pullman for everyone, even the home team!
How thin is Washington State's experience going into this weekend's game?
12 starters (including 2 walk-ons) have 2 or fewer games of experience for the Cougs going into this weekend's game against Cal. And given all those injuries you've read about this week, they can't have much depth.
