Ouch! Jason Priestley is recovering in a hospital after being thrown from a horse.

While on the set of his new TV series "The Code," the actor fell hard and was taken to a local emergency room where he found out that he suffered a concussion, according to TMZ. He stayed in the hospital overnight.

According to the report, Jason has a history of concussions and a neurologist was looking at tests to see the severity of the fall.

On Nov. 11, he took to Twitter to update his 83,000 followers on his health.

"Hey guys, thanks for all the kind words... It's true, I did get thrown off a horse on set... I got my bell rung pretty good," he wrote. "Because I have a history of concussions, they took me to see a neurologist for an assessment. He advised I take a few days off as I had suffered a concussion... But I am definitely on the mend and looking forward to getting back to work with all the wonderful people on 'The Code.'"

Earlier, he told a follower, "I'm OK... Got my bell rung."

Jason's injury history is well-documented. In 2002, he fractured his spine and suffered a concussion after crashing a race car in Kentucky.
