According to ESPN, the athlete's mother, Barbara, sent a text message to his friend Tim "Fuzzy" Hall, and reported that Lavin was able to move his hands on Saturday.
"Neuro came and spoke to T.J.," she wrote in the text message. "He moved his hands around and he gave the docs a thumbs up. He is not conscious. He's back on sedation to rest and minimize brain swelling."
Lavin, 33, who hosted MTV's Real World Road Rules Challenge for 10 seasons, was competing in a dirt qualifying round in the Dew Tour Championships in Las Vegas. While attempting a "nac nac" jump combination, he could not get his feet back on the pedals and crashed, suffering an orbital fracture on his eye and a fractured right wrist.
A tour spokesperson told ESPN that he was wearing a helmet at the time of the accident.
Lavin's business partner, Chris Aday, told the Las Vegas Review-Journal, that he believed the athlete was planning to retire after the Dew Tour Championships.
"He kept making comments like, 'Well, this is my last one,' " he told the paper.
