Chelsea striker Ben Sahar has suffered appendicitis while on-loan at QPR.

The exciting 17-year-old Israeli striker had been looking forward to his Championship debut on loan from Chelsea after notching two goals in a pre-season game against Fulham. Instead, while his new team-mates were twice coming from behind at Ashton Gate, Sahar was preparing to go under the knife at a Bristol hospital.

"We will be without Ben for four or five weeks, which is a blow, but our first consideration is his health," said Gregory after the game. "He was very ill this morning and is having surgery as I speak."
