True Blood star Stephen Moyer has injured himself falling off a horse during filming for the TV series.

Stephen, who plays Vampire Bill in the TV series based on the Sookie Stackhouse books by Charlaine Harris, was filming a stunt scene when he fell off.

“I rode behind a stuntman and we were in a forest,” he told US press.

“I came off and the horse went back and I landed on this two-foot square piece of concrete. It was the only piece of concrete in the whole forest — and I landed straight on my knee.”

He has since recovered.
