As if Northwestern's season couldn't get any worse, starting quarterback Dan Persa might be sidelined again.
Coach Pat Fitzgerald said Monday that Persa is questionable for this week's game at Indiana with turf toe in his left foot. Persa suffered the injury midway through Saturday's loss to Penn State and left the game.
The senior is wearing a walking boot, according to Fitzgerald. Persa's injury is not on the same leg as his surgically repaired Achilles' tendon, which sidelined him for the final three games of last season and the first three games of this one.
Although Northwestern won its only two games without Persa, the Wildcats' five-game slide has had little to do with its senior quarterback. Persa is completing 74.8 percent of his passes for 990 yards, and while he has thrown costly interceptions the past two weeks, he also has six touchdown strikes. If his defense bothered to help him out, Northwestern would be in much better shape.
It'll be interesting to see what Northwestern does if Persa can't play in Bloomington. Kain Colter has been the next man in, but he also has done well as a wide receiver and still seems too one-dimensional as a quarterback, as we saw after Persa left the Penn State game.
Trevor Siemian is a more prototypical quarterback and has completed 11 of 19 passes for 170 yards and three touchdowns. We'll probably see a mix of Colter and Siemian against an Indiana defense ranked 107th nationally but 45th against the pass.
