MOSCOW (AP) " A Russian sprinter who gave evidence of alleged doping involving a leading coach has been banned for four years for his own drug offenses.
The All-Russia Athletics Federation says that Alexander Khyutte received the ban from the Court of Arbitration for Sports for a failed drug test, an attempt to use a banned substance, and an attempt to avoid drug testing.
After he was accused of the offenses, Khyutte had contacted track's world governing body, the IAAF, with allegations that his former coach Zukhra Vereshchagina and other Russian athletes were involved in drug use.
The IAAF told The Associated Press earlier this month that it was investigating Vereshchagina.
Neither the IAAF nor the CAS had any immediate comment.
Athletes who give "substantial assistance" to investigations of others' doping offenses can get reduced bans, though it wasn't clear whether that was considered in Khyutte's case.
