Nick Diaz

MMA fighter Nick Diaz, not to be confused with his brother Nate, was involved in a huge brawl in Las Vegas early Wednesday morning (Aug. 24), reports TMZ.

A rep for the club said the UFC fighter went to a bathroom outside the club around 2:30 AM, and accidentally stumbled into another customer … and an argument ensued.

The report says that Nick apologized and said he didn’t want any trouble, but three other men jumped him. “I didn’t start it. They didn’t know who I was,” Nick says.

Witnesses said chairs were thrown and there was even brawling with club and casino staffers. The three guys were eventually removed by security.

Diaz is currently serving a five-year suspension from the UFC for his third failed marijuana-related drug test.
