VALENTINO Rossi's bid for a 10th MotoGP title has been thrown into disarray, with the Yamaha rider breaking his leg in a motocross crash.
Yamaha has confirmed that the 38-year-old has broken both bones of his right leg, with Rossi being taken immediately to Ospedale Civile di Urbino in Italy where he will undergo surgery "as soon as possible".
"Following an enduro training accident on Thursday, August 31, Movistar Yamaha MotoGP star Valentino Rossi was diagnosed with displaced fractures of the tibia and fibula of his right leg," a statement from Yamaha said.
"The 38-year-old Italian rider will undergo surgery as soon as possible."
Rossi's father Graziano told ANSA: "Valentino is not optimistic. They fear there is a fracture. To do the radiograph they had to cut the boot, and Valentino told me he feels very bad."
Rossi is fourth in the 2017 MotoGP championship standings, 26 points off the lead, with his home race weekend at Misano just seven days away.
His right leg is the same one Rossi broke in a nasty crash at Mugello in practice for the 2010 Italian Grand Prix, an injury that sidelined him for 41 days.
The crash is Rossi's second major incident while training in 2017 after sustaining chest injuries ahead of the Italian GP in May.
