Ben Spies broke his left wrist when he crashed a motocross bike while training Sunday.

Spies, 16, who rides for Team Valvoline EMGO Suzuki, finished second in the AMA 750cc Supersport race at Daytona and ran well under the class lap record during testing at Road Atlanta last week.

At post time it was not clear when Spies would be able to race again. He will miss next week’s Formula USA National at Willow Springs and may miss the AMA National at Sears Point May 4-6 as well.
