An amateur MMA fighter died following a fight Saturday night in South Carolina.

Tyrone Mims became unresponsive while being monitored after his fight at the Omar Shrine Center in Mount Pleasant, according to The Post and Courier. He was rushed to Medical University Hospital, where he was pronounced dead. An autopsy is scheduled for Monday.

Mims, 30, was from Augusta, Ga. The amateur event, called Fight Night at the Point and run by Conflict MMA Promotions, was being streamed online, but the video was eventually stopped and the rest of the fights were canceled.

Mims is the fourth MMA fighter to due in the US following a fight and the second this year.
