Odell Beckham Jr. wasn't the only one throwing punches Sunday in Buffalo.
An unidentified Bills player who wasn't even in uniform took a swing at Giants defensive lineman Cullen Jenkins in the fourth quarter after a play ended in front of the Bills' bench.
"I don't even know who it was," Jenkins told Newsday on Wednesday. "Who does that?"
It's unclear.
Jenkins was credited with a sack on the play, thumping quarterback Tyrod Taylor out of bounds for a loss of 2 yards. After that hit along the sideline, Bills coach Rex Ryan had words for Jenkins and the two were briefly face-to-face.
