Carl Weathers, a former NFL linebacker who became a Hollywood action movie and comedy star, playing nemesis-turned-ally Apollo Creed in the “Rocky” movies, facing off against Arnold Schwarzenegger in “Predator” and teaching golf in “Happy Gilmore,” has died. He was 76.

Matt Luber, his manager, said Weathers died Thursday. His family issued a statement saying he died “peacefully in his sleep.”

Comfortable flexing his muscles on the big screen in “Action Jackson” as he was joking around on the small screen in such shows as “Arrested Development,” Weathers was perhaps most closely associated with Creed, who made his first appearance as the cocky, undisputed heavyweight world champion in 1976’s “Rocky,” starring Sylvester Stallone.

Most recently, Weathers has starred in the Disney+ hit “The Mandalorian,” appearing in all three seasons.

Weathers played college football at San Diego State University — he majored in theater — and went on to play for one season in the NFL, for the Oakland Raiders, in 1970.

After the Raiders, he joined the Canadian Football League, playing for two years while finishing up his studies during the offseason at San Francisco State University. He graduated with a B.A. in drama in 1974.
