Red Bull KTM Factory Racing has revealed Cooper Webb will miss the final two rounds of the 2019 Lucas Oil AMA Pro Motocross Championship after injuring his knee at Unadilla last weekend.

The 2019 AMA Supercross champion suffered a bone contusion in his left knee during moto one on Saturday, which prompted him to sit out the remainder of the day. While the injury does not require surgery, Webb will need a few weeks to recover.

Fresh off his first-career 450MX overall win at Spring Creek, Webb was beginning to gain traction in the outdoor season. With podium finishes in seven motos through the first 10 rounds, he currently sits sixth overall in the 450MX championship standings.

The Red Bull KTM Factory Racing team will now solely field Marvin Musquin at the Budds Creek and Ironman rounds, where he currently sits second in the championship rankings.
