Yamaha/Graves Yamaha factory rider Damon Buckmaster and veteran racer Jerry Wood both suffered serious bone fractures in their crashes during Formula USA races Sunday at Daytona International Speedway (DIS). Buckmaster suffered multiple fractures of his right shoulder as well as a bruised lung and will not race in this coming weekend’s AMA event at DIS, according to Yamaha Team Manager Tom Halverson. Halverson also told Roadracingworld.com that Wood, who was in the emergency room at Halifax hospital at the same time as Buckmaster, suffered multiple fractures of one femur and hip. Wood, an auctioneer, is scheduled to host his annual J. Wood & Company motorcycle auction this week at Stetson University in Deland, Florida. More information will be posted as it becomes available.
