A postgame altercation followed the Buffalo Bills’ 37-34 overtime victory over the Los Angeles Rams on Monday night. Rams offensive lineman Alaric Jackson walked toward Bills linebacker Bradley Chubb at midfield and punched him in the face, according to the source’s account of the incident.

Chubb told the California Post that the game’s closeness and intensity contributed to the confrontation. He said he was fine afterward and intended to prepare for the next week. The source reported that a teammate pulled Chubb away as the exchange threatened to escalate. Jackson did not appear to comment on the incident, according to the report.

The game was tied late in regulation when Rams running back Kyren Williams scored on a one-yard run with five seconds remaining. Buffalo won in overtime on a 45-yard field goal by Tyler Bass with 1:55 left, the source reported.

The result moved Buffalo to 4-1 and left Los Angeles at 2-3. The report said Jackson was likely to face a suspension, but provided no official league announcement or disciplinary determination.
