Steve-O's Careful Return to Dancing With the Stars

The Jackass prankster won't let his injuries get in the way of tonight's performance

Welcome back, Steve-O.

I just got word that the Jackass prankster is expected to take the floor again tonight on Dancing With the Stars.

Even so, he and partner Lacey Schwimmer aren't taking any chances this time around.

"They're doing a really cool dance with non-Jackass moves," a source said. "They've learned their lesson."

A rep for DWTS confirmed his return: "Yes, he is expected to perform."

Steve-O had to ditch last week's show because he injured his back when he landed on his mic pack at the end of a flip during dress rehearsals of a salsa routine. As he was sent to the hospital, the judges had to cast their votes based on a video of the doomed performance.

Steve-O's problems first began shortly after the season premiere on March 9 when he and Schwimmer started rehearsing the salsa. He was diagnosed with pinched nerves and torn muscles.

Fellow injured contestant Steve Wozniak is also expected to perform tonight, even though he suffered a pulled hamstring during rehearsals on Friday. This is his second injury, too. He's already being treated for a fractured left foot bone.
