EVANSTON, Ill. -- Michigan State strong safety Isaiah Lewis was ejected in the first quarter of Saturday's game with Northwestern after a penalty for targeting Wildcats quarterback Kain Colter.
Colter, a senior, lined up as a wide receiver and caught a Trevor Siemian pass at midfield during the Wildcats' second offensive possession of the game. Lewis knocked Colter to the grass and jarred the ball loose. Officials assessed a 15-yard penalty and Lewis was finished for the day.
Colter left the game holding his midsection and was questionable to return.
The Wildcats then drove to the Spartans 5-yard line but stalled and settled for a 22-yard Jeff Budzien field goal and a 3-0 lead.
Michigan State (9-1, 6-0 Big Ten) is trying to wrap up the Legends Division title with a victory at Ryan Field. Northwestern (4-6, 0-6) is seeking to avoid its seventh straight loss.
