LONDON — Russian athletes involved in a major doping scandal will face disciplinary proceedings in the next three months and a race-walking coach could be banned from the sport, the International Association of Athletics Federations (IAAF) said Monday. The IAAF and the World Anti-Doping Agency (WADA) have begun a probe into Russian race-walking after a German television documentary alleged widespread doping. Russia's anti-doping agency announced last month that three Olympic walking champions, Olga Kaniskina, Valery Borchin, Sergei Kirdyapkin, as well as the 2011 world champion Sergei Bakulin and the 2011 world silver medalist Vladimir Kanaykin had been suspended for doping infringements. The IAAF said disciplinary proceedings have been opened against coach Viktor Chegin who trained at the Russian race-walking center in Saransk. — Reuters
