Michigan cornerback Jourdan Lewis is questionable for Saturday's game against UNLV.
U-M coach Jim Harbaugh said today at his press conference he was not sure of Lewis' status because that's in the hands of doctors.
"I've never really gotten into the business of predicting, when it comes to concussions," Harbaugh said. "I'm not into predicting. It's not my area."
Lewis, Michigan's top cornerback, left Saturday's 35-7 win over Oregon State with 2:50 remaining in the first half after a collision. He tried to walk off under his own power, but struggled and needed assistance to get back to the sideline.
