Malcolm Stewart faces surgery today to repair a broken femur after crashing out hard in Saturday night’s Glendale Supercross.

It’s a tough blow for the rider who was starting his first full season with a full-time 450 ride and who challenged for the win at last week’s Anaheim opener.

He lost control in the Arizona race which was red flagged while the medical teams got to him. Check out his crash in the official highlights video here.
