Ed McMahon (search), Johnny Carson's (search) former sidekick, was hospitalized after a fall in his Beverly Hills home left him with a mild concussion and a gash in his head that required stitches, his publicist said Monday.

"Mr. McMahon's prognosis is excellent and he is expected to be released from the hospital in the next few days," spokeswoman Susan DuBow said. The name of the Los Angeles area hospital wasn't disclosed.

McMahon, who turned 82 on Sunday, tripped and fell Friday afternoon, DuBow said.

He was taken to a hospital where he received several stitches in his forehead, she said, adding that he had suffered a mild concussion.

McMahon is best known as Carson's sidekick on "The Tonight Show." Carson, who retired in 1992, died Jan. 23 of emphysema at age 79.

McMahon was also co-host with Dick Clark (search) of the "Bloopers" shows and appeared year after year on Jerry Lewis' Labor Day telethon.
