Buffalo Bills offensive lineman Bobby Hart has been suspended for one game after hitting a Tennessee Titans coach.

The NFL confirmed the ban for an action at the end of the Bills' 41-7 victory over the Titans on Monday.

Hart was deemed to have taken a swing at an opposing player and missed, making contact with a coach instead, although the NFL did not identify either Titan.

In a letter to Hart, NFL vice president of football operations Jon Runyan wrote: "As both teams were heading to the tunnel, you walked directly across the field to seek out your opponent.

"You approached him near the end zone and a coach had to hold you back as others shook hands.

"Once you and your opponent were in the end zone near the tunnel, you confronted him and immediately swung at him with a closed fist, striking the head of a Tennessee coach.

"Your aggressive conduct could have caused serious injury and clearly does not reflect the high standards of sportsmanship expected of a professional."

ESPN reported Hart, who played three games for Tennessee last year before joining the Bills, would appeal against the suspension.

Having played in a quarter of Buffalo's offensive snaps during Monday's game, Hart is eligible to return to their active roster following Week 3, in which the Bills play the Miami Dolphins.
