The video, posted by TMZ on its website, shows Wolfe first having a verbal exchange with one or more persons, followed by some pushing and shoving in a group as Wolfe then throws a right-handed punch in a crowd.
TMZ reported that Wolfe was later bloodied in the altercation after being hit with an object -- possibly a bottle -- and left the VIE nightclub.
Sources with the team said police were not called about the incident.
Broncos spokesman Patrick Smyth, in a statement Tuesday morning, said: "Derek talked to us on Monday about the issue and it's been addressed internally.''
Said Wolfe's agent, Mike Simon, to TMZ: "He did not provoke the fight. He was trying to protect a friend. His recollection is that he was hit from the back with an object when he wasn't looking."
The +NFL told +The Denver Post that Wolfe is unlikely to face discipline from the league.
"We take a look at any such incident," league spokesman Brian McCarthy told the newspaper. "But it doesn't appear on its face to be something that would lead to league discipline."
