Clint Dempsey could be out for the rest of the season after suffering suspected cruciate knee ligament damage in Fulham FC's 2-0 defeat by Blackburn Rovers FC. "We won't know for certain until the scan is completed on Monday but the doctors are pretty good these days and often their initial prognosis proves correct," said manager Roy Hodgson. UEFA Europa League hopefuls Fulham are already without top scorer Bobby Zamora (collarbone injury) and defender John Pantsil (knee).
