Marc Marquez: MotoGP champion has surgery on finger injury

Marc Marquez has won one of the season's opening three races

MotoGP world champion Marc Marquez's participation in next weekend's Spanish Grand Prix is in doubt after he broke a finger during a crash in training.

Marquez broke the little finger on his left hand while dirt track racing and had a titanium plate fitted soon after.

"This will allow us to initiate functional recovery after 24 hours and give him a chance of racing at Jerez," head surgeon Dr Xavier Mir said.

Marquez's Honda team-mate Dani Pedrosa is also sidelined due to injury.

In a statement, Honda said Marquez's participation in the Spanish GP "has not been ruled out".
