Bills linebacker Andre Smith delivered a nasty and illegal helmet-to-helmet hit on Fields, which knocked his helmet off and his mouthpiece out, but the former Ohio State product bounced right back up.

After the game, Fields was asked about the hit by reporters.

“It didn’t really hurt, to be honest with you,” Fields said via ProFootballTalk.com. “I think the one thing that hurt was my helmet coming off and hitting me in the eye. But the actual hit, it wasn’t that crazy.”

In the 41-15 preseason loss to the Bills, Fields completed 9 of 19 for 80 yards and ran for an additional 46 yards.
