NEWPORT BEACH, Calif. (AP) — UFC fighter Shane Del Rosario died Monday, nearly two weeks after the heavyweight had a heart attack. He was 30.

The UFC announced Del Rosario’s death.

Del Rosario had been hospitalized in his native Orange County since Nov. 26. His manager, Jason House, said the fighter’s doctors believe he had a congenital heart disorder.

Del Rosario had been a professional mixed martial artist since 2006, also competing in kickboxing and muay thai competitions. He won his first 11 pro MMA bouts before moving last year to the UFC, where he lost his first two fights.

He was scheduled to fight at UFC 168 on Dec. 28, but pulled out last month with a rib injury.

Del Rosario graduated from UC Irvine and trained with Team Oyama in Irvine.
