Following a crash in the second 250 Class moto of the season-opening DirtBikeKidz Fox Raceway I National, Monster Energy/Pro Circuit/Kawasaki's Cameron McAdoo will be sidelined indefinitely with a leg injury.

McAdoo required assistance from race medical personnel in order to get off the track and was quoted as saying in a Kawasaki press release that he had hurt his leg prior to the incident, and that it was giving him problems in the second moto. He stressed a need to get checked out before this weekend's Toyota Thunder Valley National in Colorado and did just that. He revealed the extent of his injuries in an Instagram post - a fractured tibia - that he will now undergo surgery to repair. McAdoo will all but surely miss Thunder Valley, but no definitive timetable has been provided on his recovery and eventual return to racing.
