"Cheers" and "Frasier" star Kelsey Grammer suffered a mild heart attack on Saturday, his publicist Stan Rosenfield confirmed for FOXNews.com.
The actor, 53, was paddle boarding with his wife Camille at their Hawaiian home when he experienced symptoms, Rosenfield said. He was immediately taken to a local hospital.
He's expected to be released early this week.
Last month, Grammer said that Fox was dropping his sitcom "Back to You," calling the decision a surprise and a shame.
"They have let it go," Grammer told The Associated Press. "We were told all this time we were in good shape and we were coming back."
An online petition campaign is afoot to save the show and Grammer and his wife sent an e-mail note to friends inviting them to jump aboard. Grammer said he's "nursing a tiny hope" that CBS might pick up the show after talking with CBS CEO Leslie Moonves.
"I spoke with Les the other day and he was not completely discouraging," Grammer said, wryly.
