The remainder of the eighth season of the hit sitcom was called off by network chiefs after Sheen publicly criticised series creator Chuck Lorre last week (ends27Feb11).

But Michaels admits Sheen is still welcome to make his TV comeback on the long-running comedy show.

Discussing the possibility of Sheen booking an SNL hosting gig, Michaels tells the New York Daily News, ""Not anytime soon. But he's done it before and I'm sure he will again one day.""
