KINGSTON: West Indies all-rounder Andre Russell is facing the prospect of an extension to his one-year ban for a doping whereabouts rule violation. Jamaica's anti-doping commission (JADCO) is pushing for the maximum two-year suspension to be imposed on the 28-year-old Russell, who was banned in January for one year. JADCO chief executive Carey Brown told Reuters on Wednesday that his organisation had filed an appeal with Jamaica's five-member anti-doping Appeals Tribunal. '(JADCO) has appealed,' Brown said. Russell, a two-times Twenty20 World Cup winner, was revealed to have committed the violation a year ago after registering three filing failures in 2015. That constituted a failed drugs test under World Anti-Doping Agency (WADA) rules.
