Tennis-CAS to hear Yastremska's doping suspension appeal before Australian Open

The Court of Arbitration for Sport (CAS) said on Tuesday it has begun hearing an urgent appeal by the provisionally suspended Dayana Yastremska so a decision can be taken on her participation at next month's Australian Open.

"The CAS arbitration has commenced and the parties have agreed to an expedited procedure in order to enable a sole arbitrator to issue a final decision by Feb. 3," the CAS said in a statement.
