The actress, who has co-starred on Warner Bros.-produced “Big Bang” since 2007 and is recuperating at a L.A.-area hospital, was originally supposed to be in the episode but won’t be able to participate.

Scribes are now rewriting the episode so Cuoco’s character, Penny, won’t play a part in the plotline.

The show is on hiatus beginning Wednesday and it’s unclear whether she’ll be able to work when the cast and crew return two weeks from now.
