WATCH: What Exactly Is Mike Tyson Up To?

Former boxing champ Mike Tyson , once again, swapped the ring for the stage on Sunday night, as he strutted his stuff during the opening of the Tony Awards.

The annual theatre awards, which took place at Radio City Music Hall in New York, were led by four-time host and general theatre darling, Neil Patrick Harris.

But Tyson, who last summer performed a one-man play with a brief but impressive run of sold out performances on Broadway billed as 'Mike Tyson: Undisputed Truth', was on hand for a quick cameo appearance in which he showed he's not quite as nimble on his feet as some of his thespian peers.

Watch Tyson take over the Tony's in the video above.

The three-hour long ceremony featured performances from some of the biggest Broadway shows of the year, as well as a bevy of Hollywood cameos from nominees and presenters like Tom Hanks, Scarlett Johansson and Zachary Quinto.
