Chelsea defender John Terry is likely to be ruled out for several weeks after suffering a cheekbone fracture in the Blues' goalless draw with Fulham on Saturday. Chelsea announced that the 26-year-old will undergo facial surgery on Sunday and he is now certainly ruled out of midweek Champions League clash at Valencia. Moreover, the England skipper is set to miss his side's decisive Euro 2008 qualifiers against Estonia and Russia in October. Terry collided with Fulham's American playmaker Clint Dempsey in the first half of the Premiership game, where he was taken off at half-time. England and Chelsea will wait until further news regarding the extent of the injury sustained by the influential defender.
