American Supercross crowd favorite Kevin Windham was injured in Houston’s 13th round of the Monster Energy AMA series on Saturday night.

Windham was battling James Stewart for several laps of the second Supercross Class heat race and appeared to be setting up the past series champion for a big pass on the final turn when his right footpeg dug into the face of a jump and pitched him off.

Windham had to be assisted off the track by the Asterisks Medical Team and was unable to return, explaining the extent of his injuries in a statement released by GEICO Honda.

“I’ve hurt my left thumb and wrist and my right shoulder,” Windham said. “They took some X-rays but they were inconclusive. They put a cast on my arm and wrapped up my shoulder. I’m going back home and I’ll go to my personal doctor.

“I really have no idea how serious it is because they just couldn’t tell. It would be crazy for me to speculate on what might happen from here.”

Stay tuned for an update when we have it.
