An X-ray revealed that the Tottenham captain needs surgical help to allow the fractured shinbone to heal properly and it means he will not be able to fulfil his stated ambition of being back in the game by Christmas.
The setback could prompt Spurs to increase their pounds 2.5m bid to sign West Ham's Croat centre-back Slaven Bilic, who has been offered a year's extension of his three-year contract at Upton Park in an effort to keep him.
Tottenham's manager, Gerry Francis, said: "I never talk about players who are under contract to other clubs, but we made several bids for players, even before all the injuries we've had this season, and had them rejected. I can't see us ever trying to buy one player for, say, pounds 15m like Newcastle have for Alan Shearer, but I do have money to spend and there is no doubt I still want to get new people in if I can."
Tottenham's England striker, Teddy Sheringham, is awaiting results of a scan on his pulled thigh muscle to see when he can return to action. He missed Spurs' last defeats against Wimbledon and Newcastle after being injured while training with England.
Steve Stone's operation to repair a ruptured patella tendon in his left knee was a success, and his Nottingham Forest manager, Frank Clark, said yesterday: "The surgeon has told us that everything went well. We're already looking forward to Steve making a full recovery."
