LAS ANGELES — American sprinter Tyson Gay's former coach has been suspended for eight years for doping violations, the US Anti-Doping Agency said Wednesday. An independent arbitration panel found that Jon Drummond possessed, trafficked, and administered banned performance enhancing substances to an athlete under his care as a coach, USADA said on its website. The former Olympic relay gold medalist and Olympic coach was Gay's coach when the former world champion tested positive in 2013 for a banned substance, according to the arbitration panel decision. Gay, the US record holder at 100m, was suspended for one year in May. Attempts to contact Drummond went unanswered. – Reuters
