Tottenham full-back Ben Davies is set for a prolonged spell out after the Premier League club confirmed he had sustained ligament damage to his left ankle.
Wales international Davies, 26, suffered the injury in head coach Jose Mourinho's first game on Saturday and was withdrawn 15 minutes from time, shortly after West Ham scored their first goal in Spurs' 3-2 win.
Davies did not feature when Mourinho's men came from behind to beat Olympiacos 4-2 in the Champions League on Tuesday and he was spotted on crutches and with his foot in a boot coming through the mixed zone after the game.
