The Poison frontman is suing over being hit in the head by a set piece after performing at the awards show.
He claims show organizers never explained that the set would be changing after the band performed, "Nothin' But a Good Time." He also claims the show could have prevented the incident from airing, but chose not to.
Michaels was hospitalized in April 2010 and doctors found he had a brain hemorrhage and he later suffered a warning stroke, which the musician says nearly killed him.
Phone and e-mail messages to spokespeople for the Tonys and CBS were not immediately returned.
