WATCH: Terrell Owens brutally knocks heckler out cold outside CVS

Terrell Owens had a reputation for being a bit of a loose cannon during his days in the NFL. And the former wide receiver appears to have not lost his edge with age. According to a video posted by TMZ Sports, the wide receiver was spotted outside a CVS throwing hands with someone else.

In the video, Owens, the white-shirted combatant, is seen fighting with someone. The fight didn't last long, as he knocked the other fighter to the ground within 30 seconds for a moment before popping back up. As the fight erroded back into a what appeared to be a heated conversation, the person recording the incident was heard commenting live, saying it was "epic."

The person recording the fight was sitting in their car. They were recording through their driver’s side window across what appeared to be a dimly-lit street. Multiple by-standers are seen watching the events unfold. After knocking the heckler to the ground, the former wide receiver walked away.
