Carson's sidekick suffers house fall

US chat show legend Johnny Carson's beloved sidekick Ed McMahon spent his 82nd birthday in a hospital over the weekend.

The US television personality was admitted to hospital in Beverly Hills, California, with mild concussion after falling at his home.

Insiders claim he required stitches for a lesion on his head but is otherwise fine and was kept in hospital over the weekend for tests.

He is expected to be released from the hospital later this week.

Carson died earlier this year.
