Tottenham Hotspur goalkeeper Carlo Cudicini has suffered "potentially life-changing injuries" in a motorbike accident in east London, police said.
He was taken to hospital after his BMW bike was involved in a collision with a car in Walthamstow at about 1030 GMT.
He has fractured his wrists and injured his pelvis but a spokesman for the north London club said they were still waiting for hospital test results.
The Italian, 36, signed from London rivals Chelsea in January this year.
The female driver and a child passenger walked away from the Ford Fiesta Cudicini was in collision with and did not need hospital treatment.
No arrests
The accident happened on Forest Road.
A Metropolitan Police spokesperson said: "A 36-year-old male suffered injuries described by the London Ambulance Service as possibly life-changing and was taken to an east London hospital for further assessment and treatment.
"No arrests have been made."
A statement on Tottenham's website said: "Carlo Cudicini has fractured his wrists and injured his pelvis after being involved in a road accident this morning.
Free transfer
"The 36-year-old Italian goalkeeper has been admitted to hospital and undergone scans under the supervision of club medical staff.
"The club will update supporters on Carlo as soon as there is any further information."
Cudicini was signed by manager Harry Redknapp on a free transfer and has made eight appearances standing in for the injured Heurelho Gomes.
He spent almost 10 years at the west London club after spells at AC Milan and Lazio.
His father Fabio was AC Milan's goalkeeper in the 1960s.
Anybody else amazed that a professional footballer is allowed to use a motorbike? Players are assets to clubs, I'm very surprised that a club would let one of their assets ride around on a motor bike.
