Stan Rosenfield says Grammer is "resting comfortably" in an undisclosed hospital after being stricken Saturday. Rosenfield says the 53-year-old actor will be released early this week.
Rosenfield says Grammer — the star of "Cheers," "Frasier" and the recently canceled Fox sitcom "Back to You" — was paddle-boarding with his wife, Camille, when he experienced symptoms.
The couple lives in Kona, on Hawaii's big island.
Rosenfield says Grammer was immediately taken to an area hospital where it was determined that he had suffered a "mild heart attack." The spokesman says he is unaware of any history of heart trouble for Grammer.
