Mountain biker David Mock has been suspended by the US Anti-Doping Agency after testing positive for marijuana. His punishment was reduced after he successfully completed an agency anti-doping education program.

He accepted a three-month period of ineligibility, which began on December 11. However, his sentence was reduced to time served after he completed the USADA's program on December 16.
