The Court of Arbitration for Sport (CAS) is expecting a flood of appeals once athletes identified in the McLaren report into doping in Russia are sanctioned, the bodys general secretary said on Tuesday.

"We would expect several hundred cases because there were a thousand infractions," CAS's Matthieu Reeb told a press conference in Geneva.

Reeb said that once international sports federation had taken out disciplinary proceedings against competitors, he expected many of those punished would appeal to CAS.

"Some athletes, I expect, will let the matter drop," he said. "But others will certainly go ahead (with an appeal to CAS)."

Canadian lawyer Richard McLaren, who has previously accused Russia of state-sponsored cheating, said in his final report commissioned by the World Anti Doping Agency (WADA) that more than 1,000 athletes in the summer and winter Olympics and Paralympics "can be identified as being involved in or benefiting from manipulations to conceal positive testing."

Information on 695 Olympic athletes has already been sent to sports federations.
