HERZOGENAURACH, Germany - Adidas has suspended its sponsorship of Tyson Gay after the American sprinter's positive doping test.
After learning that a banned substance was detected in a May out-of-competition test, Gay pulled out of the upcoming world championships.
In a statement, Adidas says "we are shocked by these recent allegations, and even if we presume his innocence until proven otherwise, our contract with Tyson is currently suspended."
The sportswear giant has backed Gay since 2005 and says such sponsorships are terminated "if the athlete is found guilty of the possession, or use of drugs, or any other prohibited substance by the relevant governing sports body having jurisdiction over the athlete."
Gay has said he will have his "B" sample tested soon, possibly as early as this week.
