New video shared by TMZ appears to show Denver Broncos defensive end Derek Wolfe throwing a punch inside a bar.

The fight reportedly happened Saturday night inside a Denver nightclub. 

A man who appears to be Wolfe argues with people inside of the club before punching someone, TMZ says. Witnesses told TMZ Sports that a guy was taling trash to Wolfe before pushing started.

They also said Wolfe was hit with a glass bottle and left the club covered in blood.

It's not clear by the angle of the video if Wolfe made contact with anyone.

The Broncos haven't commented and Wolfe's agent did not respond to TMZ, according to their story.

Wolfe, 26, just finished his fourth year with the Broncos. The team signed him to a four-year contract extension in January worth $36.7 million.

Wolfe missed four games last season. He was suspended for violating the NFL's policy on performance-enhancing drugs.
