Myles Garrett of the Cleveland Browns was suspended for at least the rest of the season on Friday for pulling off the helmet of Steelers quarterback Mason Rudolph and hitting him in the head with it.
The suspension is the longest for any player for a single on-field incident, and the N.F.L. said in a tweet on Friday that Garrett would need to meet with league officials to be reinstated next season.
Two other players, Steelers center Maurkice Pouncey and Browns defensive tackle Larry Ogunjobi, were also suspended, and the Browns and Steelers were fined $250,000 each.
