A Yamaha spokesman said the Court of Arbitration for Sport (CAS) was meeting in Lausanne on Wednesday (October 11) to make a final ruling on the doping case involving the team’s Japanese rider Noriyuki Haga.
Haga was docked 45 points and suspended for three weeks after failing a dope test for the banned stimulant ephedrine at the season-opening race in South Africa in April.
If the CAS decides to reverse the International Motorcycling Federation?s (FIM) ruling, and reinstate Haga’s points, he will be back in the running for the title.
Honda’s Edwards has a 52-point lead over Haga with just the final round of the championship – worth a maximum 50 points – to come at Brands Hatch in England this weekend.
Yamaha have appealed on the grounds that Haga had unwittingly taken the substance through a cold remedy or mineral supplements. The affair has hung over the championship for nearly six months, with the FIM twice upholding the sanctions.
