Monster Energy Kawasaki rider Ryan Villopoto will not race the second moto at Hangtown. While riding this week in preparation for the event, Villopoto injured his knee. After riding the first moto, he and the team have decided not to start the second."We know Ryan is a tough competitor," said Monster Energy Kawasaki Team Manager Mike Fisher. "He has been riding great and it is a shame he can't be out there on the track. We will continue to evaluate his condition heading into the next event."
