Nike did not 'systematically dope' runners: CEO Parker

Nike never participated in efforts to "systematically dope" runners, CEO Mark Parker said in an email obtained by AFP Wednesday after sponsored coach Alberto Salazar was given a four-year ban for doping.

"Nike did not participate in any effort to systematically dope any runners ever; the very idea makes me sick," Parker wrote in the email sent to employees on Tuesday following the revelations about the athletics coach.
