Miami Dolphins safety Bobby McCain will be disciplined by the team for a verbal confrontation with a 13-year-old boy and for allegedly spitting in the face of another Bills fan following Miami's loss at Buffalo.

Coach Brian Flores said he discussed the incident with McCain on Monday, the day after the Dolphins' 31-21 loss. Flores wouldn't say whether McCain will miss playing time as part of the discipline.

Erie County Sheriff's Office spokesman Scott Zylka confirmed that police are investigating fans' complaints, working with the Bills and the NFL in reviewing stadium security video. The Buffalo News first reported the investigation.

The fan, 28-year-old Dylan Wentland, told The Associated Press he was standing at the ledge overlooking the tunnel when McCain ran up and spit in his face following the game. Wentland said he and McCain exchanged words before the game when McCain twice threatened to spit at a teen, once before pregame warm-ups and a second time while heading out to the field before kickoff.

Wentland told the Buffalo News that McCain's threat to spit on the teen came after the boy shouted to the safety that he was "irrelevant."

The Bills declined to comment. The NFL did not immediately return a message seeking comment.
