BEN Cohen will not make the trip to Sixways for the Premiership match between Northampton Saints and Worcester.

Cohen is expected to be out until the middle of next month after fracturing his cheekbone during Saints' European Challenge Cup match with Narbonne.

That rules the England winger out of the meeting in Worcester on January 7.

Cohen's last appearance at Sixways was a man-of-the-match performance for Northampton in their Powergen Cup victory over Warriors.

He then marked his return to the England set-up with a try against Australia in November.

Saints director of rugby Budge Pountney said: "Ben took a knock to the cheekbone that has given him trouble before. He has got a crack on it and it needs an operation. It looks like he will be out of action for four weeks."
