Michael Diamond, a 63-year-old racer from St. Augustine, Florida, has accepted a two-year doping suspension after refusing to submit a sample during an out of competition test.
The U.S. Anti-Doping Agency announced the suspension Friday.
USADA said Diamond refused to submit a sample on October 8. According to the USA Cycling website, Diamond, racing unattached, finished fifth that day in the Florida time trial championships.
In addition to the suspension from competition, Diamond is also disqualified from all competitive results obtained on and subsequent to that date.
