MotoGP champion Marquez has surgery on broken hand

Marc Marquez will still travel to the Japanese Grand Prix despite suffering a broken hand in training.

The defending MotoGP world champion broke the fifth metacarpal on his left hand after suffering a fall while training on bicycles with brother Alex on Tuesday.

Marquez underwent successful surgery and will undergo more checks prior to the 15th Grand Prix of the season at Motegi on October 11.

"We have operated on Marc Marquez to treat a torsion fracture of the fifth metacarpal of his left hand," surgeon Dr Xavier Mir said.

"The surgery consisted of a reduction and internal fixation of the bone, through screws for compression and a neutralising titanium plate with six holes.

"After the insertion, the soft tissue has been closed up and we have placed a protective bandage around the finger, supporting it with the adjacent finger. Marc will remain in hospital for 24 hours, and in 48 hours will begin functional rehabilitation."

Marquez trails championship leader Valentino Rossi by 79 points with four races remaining and could be eliminated from title contention at Motegi.
