Funnyman Damon Wayans has scrapped a series of stand-up shows following a diabetes-related medical emergency.

The comedian was supposed to perform in Missouri on Saturday night (21Feb15), but sources close to Wayans tell he was unable to fly to the gig because of his ongoing battle with Type 2 diabetes.

Insiders reveal there are more dates Wayans is planning to reschedule, including a series of dates in Buffalo, New York next month (Mar15).

While his exact diagnosis has yet to be revealed, sources tell Tmz that he might be able to perform shows around his home in Los Angeles, but all out-of-state gigs are being put on hold.

Wayans has assured his fans he's going to be Ok, tweeting, "#diabetes #im alright #thankforthrloveandsupport."
