Browns defensive end Myles Garrett is taking full responsibility for his helmet-swinging attack on Steelers quarterback Mason Rudolph on Thursday Night Football.

Garrett tore off Rudolph’s helmet and hit him with it after taking the quarterback to the ground late in the game.

“I lost my cool and I regret it,” Garrett said. “It’s going to come back to hurt our team. The guys who jumped into the scrum, I appreciate my team having my back, but it never should have gotten to that point. It’s on me.”

In addition, Steelers center Maurkice Pouncey will likely face league discipline for kicking Garrett in the head while defending his quarterback.

The Browns won the game 21-7.
