ABERDEEN, Wash. (AP) — A mixed martial arts fighter bout in Aberdeen on Saturday has died at Harborview Medical Center in Seattle.

 the fighter passed away Monday evening after suffering kidney failure.

He had finished his match during an event at the SouthShore Mall and had returned to the dressing room when he collapsed. Fight promoter Scott Bean says the man, who is from Aberdeen, initially seemed OK after his fight, other than being exhausted. But he collapsed, wasn’t breathing and had no pulse when Bean and a nurse started CPR.

He was brought to a local emergency room before being transferred to Harborview.

His identity has not been released.
