Based on reports from the IBJJF Austin Open, a black belt from Gracie Barra attacked another student from a competing school after that student celebrated his victory.

The student secured a take down in the final seconds of his match to get the victory. Obviously he was pumped up and caught in the moment as he celebrated on the mats with his teammates. This did not sit well with the unnamed Gracie Barra Blackbelt who broke from behind the barriers, threw a chair at the student and from the looks of it, threw a punch.
