Actress Kaley Cuoco, who plays Penny on “The Big Bang Theory,” broke her leg last weekend when she fell off a horse. Cuoco is recovering in a Los Angeles hospital, according to TMZ.

The actress won’t be able to participate in this week’s recording of the hit CBS series. Producers said they would work around Cuoco’s absence for this episode.

There is also some question as to whether she’ll be back to film the next episode. If that’s the case, the character of Penny may have to be “written around” until Cuoco can return to work.

“The Big Bang Theory” is headed into its fourth season with a big move to Thursdays next week. The series also scored a best actor Emmy for Jim Parsons at the recent Emmys.
