HRC Honda Chase Sexton suffered a huge off at round seven of the Monster Energy AMA Supercross series on Saturday, despite leading the main event.

As the gate dropped in the 450SX class main event, Sexton found himself in second with his eyes set on the leading Cooper Webb. Just over five minutes in, the 22-year-old made an impressive pass in the turn after the finish. Sexton led 17 laps of the 20-minute-plus-one-lap race before he tucked his front wheel in a rut on a jump face. With only two laps remaining, Sexton was tossed into the following jump. The Illinois native struggled to get up, and he was escorted off the track to be evaluated at the Alpinestars Medical Unit. Although banged up, Sexton felt relatively well when he left the venue, but officials will have him undergo concussion protocol this week.
