It seemed like something out of a pro wrestling broadcast: head-butting a referee in the chest, followed by an ejection.
It wasn’t a choreographed move by Lions linebacker Jamie Collins Sr. in Sunday’s game against the Chicago Bears, when he made contact with one of the officials, Alex Kemp, in the second quarter.

Kemp immediately threw a penalty flag and announced that Collins was ejected for making contact with an official.
“It was a mistake; nothing was intentional. It is what it is. They called it and they threw me out,” Collins said Thursday.
