The skating legend suffered a sheared pelvis with a severe hematoma, according to his website:
Tony took a hard fall Saturday at the Downtown Disney demo and left by ambulance. Many people have been expressing their concern, and Tony wanted to say thanks to everyone for the well wishes. Tony continues to post updates on his Twitter feed.
