Stephen Colbert's disdain for all things left is growing.

The host of "The Colbert Report" revealed on Thursday night's show that he broke his left wrist while running around the New York studio before taping a recent episode. Colbert removed a large "No. 1" foam hand to unmask a small cast.

"I didn't want to draw attention to it. I didn't want to play on your sympathy," Colbert said before dramatically grimacing.

The fall happened June 27, before the show went on a two-week hiatus, a spokesman for Comedy Central said Friday. Colbert, 43, was only recently fitted with a cast.

"To be honest, I'm not entirely sure how it happened," the mock right-wing talk-show host told his audience. "My director Jimmy is suggesting I might have broken my wrist ... before the show."

Slow-motion footage was then shown of Colbert running around the set to "pump up" the crowd. Beyonce Knowles' "Ring the Alarm" was played over the footage, alluding to the singer's fall while performing the song during a concert Tuesday in Orlando, Fla.

As Colbert rounded his "C"-shaped desk and headed to high-five his audience, he slipped and fell backward.

"Yeah, that might have been it," he deadpanned.
