UFC Hall of Famer Randy Couture suffered a heart attack on Wednesday and is currently in intensive care at an L.A. hospital, TMZ Sports has learned.
The 56-year-old legend -- a 3-time UFC Heavyweight champ -- walked himself to the hospital on Wednesday after feeling something was off after a workout at the Unbreakable MMA gym in L.A. He was admitted and treated immediately. The good news, sources close to Randy tell us he's expected Randy to make a full recovery.
In fact, Couture fought competitively late into his 40s ... taking on Lyoto Machida for the UFC Lightweight Championship in 2011 when Randy was 46 years old. Couture lost that fight, but still, amazing.
Couture also built a career as an actor starting with a cameo on the CBS show, "The Unit" which snowballed into bigger roles in bigger projects.
