Positive drug tests for teammates saddens me, says BoltThe triple world record holder, Usain Bolt, who won the 100m in 9.91sec in the London Grand Prix at Crystal Palace, recently said he was shocked to learn that five Jamaican athletes failed to clear a test for banned substances.

Bolt said that the failed drug tests are backward steps for the sport.

It is speculated that two of the five accused athletes belong to the Racers Track Club, the same club as Bolt, and are coached by Glen Mills.
