Cudicini signed for Spurs from Chelsea in January
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.
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.
"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 Chelsea, making more than 200 appearances after signing for the west London club from Italian side Castel di Sangro, following earlier brief spells at AC Milan and Lazio.
His father Fabio was AC Milan's goalkeeper in the 1960s.
A statement on Chelsea's website read: "Chelsea Football Club sends our best wishes for a full and speedy recovery to Carlo Cudicini who has been involved in a road accident today."
