And Mayfield decided to celebrate by headbutting teammates without wearing a helmet.

The 27-year-old was spotted doing the same with his former team, the Carolina Panthers, earlier this season.

He was released by the Panthers just this week and picked up by the Rams without a waiver.

And Mayfield led a game-winning 98-yard drive on his LA debut with less than two minutes remaining.

The former No. 1 overall was cheered on by the win.

And he was spotted on TV cameras banging heads with teammate Robert Rochell.

Needless to say, his teammate wore a helmet.

Mayfield finished with 230 yards and a touchdown in a 17-16 win.

He found Van Jefferson on a 23-yard touchdown reception with just 10 seconds left for the game winner.

Mayfield said: “I don’t know if you could write it better.

“Obviously we’d like to be a little less stressful, but it’s a hell of a story, I’ll be honest with you.”
