Michigan State safety Nehemiah Warrick delivers a vicious helmet-to-helmet hit to Wisconsin receiver Kyle Jefferson in the final minute of the first half of Saturday’s game at Madison, won by the Badgers, 37-34.

With help, Jefferson eventually got to his feet and made it to the bench. He didn’t return.

“He was real close to being able to get back in there, but he couldn’t answer all the right questions in the short amount of time,” Badger coach Bret Bielema said.
