Simply "inexcusable". That's the only conclusion you can have after watching video of an NFL player swigging a helmet and hitting the Pittsburgh Steelers quarterback with it during Thursday night's game between the Cleveland Browns and the Pittsburgh Steelers.

Cleveland Browns defensive end Myles Garrett ripped off Pittsburgh quarterback Mason Rudolph's helmet and hit him with it in the head in the final seconds as the Browns' 21-7 win over the Steelers on Thursday night ended with a wild brawl between the rivals.

Garrett faces a likely suspension for his actions, and Steelers center Maurkice Pouncey will likely be disciplined for kicking Garrett in the head.

Players from both sidelines spilled on the field during the melee, which began after Garrett wrestled Rudolph to the ground well after he completed a screen pass on a meaningless play. Garrett, Pouncey and Browns defensive tackle Larry Ogunjobi were ejected.

Rudolph got his hand on Garrett's helmet first as the players wrestled on the ground, but Garrett escalated the brawl after he got back on his feet. He yanked the helmet off Rudolph and swung wildly, hitting the quarterback on the top of the head. Rudolph threw his arms in the air in disbelief after the impact, and Pouncey retaliated by punching and kicking Garrett.

After the game, Myles Garrett told reporters:

“I lost my cool and I regret it. 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.”

Browns quarterback Baker Mayfield ripped into Garrett, calling his actions “inexcusable.” He was correct.
