UFC fighter Shane del Rosario died Sunday at the age of 30.
The heavyweight suffered cardiac arrest Nov. 26 brought on by two heart attacks. He was put on life support at Hoag Memorial Hospital Presbyterian in Newport Beach, Calif., but taken off of it last week after he showed signs of brain activity.
“The entire organization sends its deepest condolences to Shane's family and friends,” the UFC said in a statement.
Doctors believed del Rosario suffered from a congenital heart disorder, according to his manager Jason House.
“RIP to one of the best people I've ever had the honor to have in my life and call my best friend,” training partner Ian McCall tweeted Monday.
Between the UFC, Strikeforce, M-1 Global, ShoXC and King of the Cage, del Rosario accumulated an 11-2 record in mixed martial arts.
