West Ham United can confirm that Winston Reid has undergone successful ankle surgery at a central London hospital.

The centre-back suffered a high ankle sprain in training on Tuesday 5 November and, following diagnosis by the Club's medical staff and a scan, underwent a procedure to repair the syndesmotic ligaments that connect the tibia and fibula in his lower right leg. He will soon begin intensive rehabilitation, but no timescale has yet been set for a return to first-team action.

Head of sports science and sports medicine Andy Rolls explained: "Winston had an operation on his ankle injury to stabilise the joint. This procedure went well.

"He will now convalesce for a few days before starting his rehabilitation."

Reid has made 92 appearances for West Ham since joining from Danish side FC Midtjylland in summer 2010, scoring five goals.

The defender was voted Hammer of the Year last season before making a strong start to the current campaign, highlighted by him scoring the opening goal in the 3-0 Barclays Premier League victory at Tottenham Hotspur in October.
