With tensions between Honda and Yamaha still high, and fans and the paddock polarised, all riders and team managers will meet with Carmelo Ezpeleta, chief executive of MotoGP commercial body Dorna Sports, and FIM president Vito Ippolito on Thursday afternoon.

An FIM statement said the gathering had been called “following the events that occurred at the Malaysian Grand Prix and further developments over the following week and given the exceptional circumstances.”

The traditional pre-race press conference that takes place at every grand prix has been cancelled for Valencia.

Last week Ippolito issued an opening letter in which he called on the factions involved in the row to stop ‘poisoning’ MotoGP and causing ‘anarchy’.

Rossi and Marquez’s Sepang collision was the culmination of growing bitterness following previous incidents between the pair this season, and amid the Italian’s accusations that Marquez was actively trying to hamper his championship bid in the preceding race at Phillip Island.

Race direction gave Rossi three penalty points on his licence for taking Marquez out in Malaysia, triggering a back of the grid start for the Valencia title decider, which Rossi goes into with a seven-point lead over Yamaha team-mate Jorge Lorenzo.

Rossi has lodged an appeal against the verdict with the Court of Arbitration for Sport.
