William Shatner Faces Surgery After Being Thrown By a Horse

"I ride the horses that can compete in equine skills, which is fast down and ends on a sliding stop," he said. "And the horse that I owned, I came off.

"And she had a habit of going too far, like six inches to the side," he added. "And I’m riding it. And I’m ready. And she goes [too fast and sent him flying]. I’m not a young stuntman anymore. I started to roll but hit the dirt with my shoulder. So, I wrecked my shoulder."

Shatner told the crowd he was scheduled to undergo a "new type of shoulder operation called a reverse something or other" March 11.
