After sustaining a head injury during filming in New York last July, she has decided to leave the show in order to fully recover.
"It is with deep regret to inform everyone that due to my injuries, I am unable to return to 'The Good Wife' at this time. Getting better slowly and thank you everyone for your concern," she said in a statement provided to ABC News by her publicist.
Chenoweth will still appear on the show's Sept. 30. premiere, kicking off its fourth season. Her rep confirmed that she "may return in the future but right now she needs more time to heal."
Chenoweth was injured filming a scene for "The Good Wife" in Brooklyn" when "a gust of wind blew a lighting silk out of place striking actress Kristin Chenoweth," CBS said in a statement in July.
A witness said Chenoweth was hit "square in the head" and was "knocked out cold," according to TMZ.
As of July 12, Chenoweth had been released from the hospital and was at home recovering.
Chenoweth, 43, won a Tony Award for her role in Broadway's "You're a Good Man, Charlie Brown" and an Emmy Award for her work on "Pushing Daisies." She also appeared in the Broadway box office smash-hit "Wicked" from 2003-04.Also Read
