Alberto Contador suffered a broken tibia during the tenth stage of the Tour De France.
The Tinkoff-Saxo rider crashed at 60-70kmh on a downhill section but got back on his bike and rode for ten kilometres only to get off due to the amount of pain he was suffering in his right knee.
Tinkoff Saxo Team boss Bjarne Riis told the media: Alberto has a broken tibia. It's not a bad fracture but he needs surgery.
"He's in a lot of pain and is getting stitches.
"Mentally he's destroyed, of course. He was in the shape of his life. This was his Tour. It's a mess. We were here to win the Tour de France. He's in super good condition, never better. It's a big, big pity."
