Michigan State safety Isaiah Lewis has been ejected from Saturday's game against Northwestern for a targeting penalty.
Lewis was flagged after drilling the Wildcats' Kain Colter as he tried to catch a short pass from Trevor Siemian early in the first quarter, jarring the ball loose. Colter, the Wildcats' quarterback, was split out wide.
Colter stayed down for a moments and walked off clutching his midsection.
