Russian sprinter Alexander Zverev has been banned for nine months by the International Paralympic Committee (IPC) for a violation of its anti-doping rules.
The IPC confirmed in an official statement that Zverev "returned an adverse analytical finding for Cannabinoids in a urine sample" following an IPC Athletics Grand Prix meeting in Germany on June 20.
Zverev has subsequently been sanctioned by the IPC, who have backdated the ban to August 6 when he was provisionally suspended meaning he cannot compete until May 5 2016.
The ban follows last week's announcement from the IAAF that the All-Russia Athletic Federation (ARAF) is provisionally suspended from athletics amid allegations of state-sponsored doping.
The IAAF acted following a recommendation of an independent commission, established by the World Anti-Doping Agency, who called for ARAF to be banned amid allegations of "corruption and bribery" at the highest levels of international athletics.
