Jackass star Steve-O received a broken nose from Mike Tyson after running into his fist in one of a series of ridiculous events at the Charlie Sheen roast Monday night.

Steve-O intentionally sprinted into Mike Tyson's fist, who was standing on the other side of the stage with his arm outstretched, as a promise to Sheen, standing nearby watching.

I told Charlie Sheen that I was so grateful to be a part of his roast that I was going to attempt to get a black eye from Mike Tyson, Steve-O said. I dove face-first into Mike Tyson's fist, although it was my forehead that landed on it that first time

Not satisfied with the first attempts to run into Tyson, Steve-O tried a final time at the end of the show, which resulted in a broken nose.

It wasn't until the end of the show that I was allowed to give it another proper try, Steve-O said. It took two more tries at the end of the show, but I ended up getting it done.

For Steve-O, a broken nose is common injury, as he calmly declared Broken nose, broken nose right before an audience member offered to pop his nose back into place, an offer which he obliged.

I couldn't believe it, it hurt like hell, but he managed to pop the bone right back into place, he said. I think my nose will actually wind up straighter than it's been since Bam Margera broke it on the set of Jackass 3D.

Steve-O apparently seemed pleased he received an injury during the Sheen Roast, posting photos of himself after on his WhoSay and Twitter accounts, with the caption, My face is a mess. Here's a good photo.

What a great deal, I get to say that I got two black eyes and a broken nose from Mike Tyson, and I'm going to come out of it looking better than I did before it happened, Steve-O said.

Charlie Sheen was just as pleased as he tweeted to the Jackass star, That's commitment my friend. Funny as hell.
