The British Olympic Association are reportedly expected to lose their court case against the World Anti-Doping Agency.

The BOA appealed to the Court of Arbitration for Sport after the Anti-Doping agency attempted to overturn the governing body's lifetime Olympic ban for athletes found guilty of taking drugs to enhance their performance.

It is understood that CAS are expected to reject the BOA's argument with an announcement being made next week, according to BBC Sport.

If the changes are permitted then the likes of British sprinter Dwain Chambers and cyclist David Millar will be allowed to compete in this summer's London Olympic Games.
