The MotoGP title battle will go down to the final race of the season after Dani Pedrosa won a dramatic Malaysian Grand Prix on Sunday that could still see championship leader Valentino Rossi disqualified.

Rossi finished third behind title rival Jorge Lorenzo to allow the Spaniard to close within seven points, but the seven-time premier class champion will await the outcome of an official inquiry to see if he keeps his points.

Prior to the race, Rossi had claimed former champion Marc Marquez was trying to help fellow Spaniard Lorenzo and the pair took their war of words onto the Sepang International Circuit in stunning fashion.

The duo swapped places and touched wheels a number of times until lap 13 when Rossi appeared to slow at Turn 14, force Marquez wide and then flicked out a knee, which resulted in his rival's Honda sliding into the gravel.

"For me it's clear, Valentino kicked the bike of Marc ... but we need to wait until the end of the race before the officials make a decision," Repsol Honda team principal Livio Suppo said in a televised interview.
