Adidas has recently suspended its sponsorship deal with American sprinter Tyson Gay after admitting to testing positive for a banned substance called oxilofrine.
Both Tyson Gay and Asafa Powell, the two fastest sprinters in the world this year, have both tested positive for the banned amphetamine oxilofrine. Both have insisted they are not cheats. Oxilofrine is a stimulant that is used to treat low blood pressure and increases adrenaline production, boosting endurance, alertness and oxygenation of the blood. Oxilofrine is a banned substance by WADA
“Adidas has a clear policy on doping and drug use – each of our agreements with our athletes including a clear clause which states that the agreement shall be terminated by Adidas 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.”
Adidas has sponsored Gay since 2005 and the brand said he played a central role at the launch of its Olympic sponsorship in 2007.
