Jahlil Okafor was involved in a fight outside a Boston nightclub early Thursday morning, according to a video obtained and published by TMZ.
Okafor is seen shouting at several individuals and then shoves a man to the ground.
Okafor then punches a man after at least one person tries to restrain him, knocking him to the ground again.
At the start of the video, Okafor can be heard shouting to someone, "We got money, you broke ass . . ." He utters a racial slur.
Boston police don't plan on investigating the fight unless someone involved comes forward to say they were victim of a crime.
"Apparently, they said: 'The 76ers suck and you guys are all losers. You'll never win a game,' " a source close to Okafor told ESPN's Jeff Goodman.
"I was around the corner when it happened. I saw him a minute after he knocked the dude out," the source said. "I think the guy was just talking s---. Saying the Sixers suck."
