Michaels suffered a busted lip and broken nose when he was hit in the head by a piece of scenery during a production number. In his lawsuit, Michaels claims the accident contributed to a brain hemorrhage in April 2010 that nearly killed him and that he continues to deal with effects from the injury and brain bleeding that left him hospitalized last year.

Michaels is the lead singer of Poison, one of the rock groups whose songs are featured in the Broadway musical Rock of Ages.

So far, CBS has declined comment and no statement has been issued by the Tony Awards.
