The world's top-ranked cyclist, Laurent Jalabert, could miss the rest of the season after sustaining a fractured skull and breaking his collarbone during a Sunday race in Spain, his ONCE team said.
Jalabert was transferred to a hospital in Madrid on Sunday night and released from the emergency ward Monday morning. The hospital said Jalabert was "conscious and in a stable condition without complications."
The fall came halfway through the opening stage of the Tour of Castille and Leon.
"It was a stupid accident," said ONCE team physician doctor Nicolas Terrados. "He doesn't even remember what happened."
It was the second serious fall in the 30-year-old Frenchman's career.
Jalabert was out of action for nine weeks in 1994 after breaking his nose and cheekbone and losing four teeth in a sprint-finish crash on the first stage of the Tour de France.
