LAUSANNE: Grigory Rodchenkov, the former Moscow laboratory director who turned doping whisteblower, will testify at the CAS appeal hearings of up to 42 banned Russian athletes writes KEIR RADNEDGE.

A report in the Frankfurter Allgemeine Zeitung attributes Rodchenkov’s decision to a comment from his American lawer Jim Walden.

In reply to an email question, Walden said: “Yes, he will testify, but from afar.”

Even so, the hearings by the Court of Arbitration for Sport will provide the first opportunity for any Russian to challenge Rodchenkov on his revelatory statements about the doping conspiracy scandal.

Some 42 Russian competitors are challenging Olympic disqualifications imposed by the disciplinary commission of the International Olympic Committee on the basis of Rodchenkov’s statements about their cheating during the Sochi Winter Games of 2014.

The hearings begin on on January 22 and sport’s supreme court has promised decisions on or before January 31, certainly ahead of next month’s Winter Games in PyeongChang.

Rodchenkov, who will presumably be available via video link, was the head of the anti-doping laboratory in Moscow and responsible for its Sochi operation during the 2014 Games.
