The 22-year-old shot-stopper was involved in a collision with the frame of the goal when trying to save QPR striker Djibril Cisse's shot during last Sunday's 1-1 draw at Loftus Road, and manager Brian McDermott has confirmed he faces a spell on the sidelines.
"Alex has seen a consultant, he has a shoulder joint problem and will be out for a little while," McDermott was quoted as saying on the club's official website.
