ANDY HAZELL, Gloucester's breakaway forward, will be out of action for three weeks after scans diagnosed a tear to ligaments in his knee.
The England international limped out of Gloucester's EDF Energy Cup victory over the Dragons on Friday and will now not feature until after Christmas.
It means he will certainly miss Gloucester's back-to-back Heineken Cup matches against Bourgoin and potentially the Guinness Premiership derby against Bristol.
"We have developed a squad so we can cope with injuries to key individuals like Andy," said head coach Dean Ryan. "With the very nature of how Andy plays the game, he will pick up injuries from time to time and we have to manage that.
"It is obviously a blow not to have a player of his energy in the squad for a couple of weeks but we have plenty of options available to us and now we need to concentrate on getting his injury right."
Hazell, who was named the South West rugby player of the year on Sunday night, has made six appearances in all competitions this season.
Speaking straight after the game, skipper Billy Twelvetrees told GRTV that losing at home to Bath, in front of a tremendous home support, was desperately disappointing and that the whole team were hurting in the dressing room.
Speaking to the local media this week, Richard Hibbard expressed his excitement ahead of the West Country derby and that there is an extra spring in the step of the Cherry and Whites ahead of the tough challenge.
With such a short turnaround between the two games, and Gloucester looking to reintegrate several players into the line-up after the Autumn international series, Tom Savage told GRTV that the Cherry and Whites will keep changes to a minimum for the European Rugby Challenge Cup game in Zebre on Saturday.
On a tough evening at Kingsholm, Gloucester could escape neither a suffocating Bath defence, nor the whistle of referee Greg Garner as six penalties and a penalty try paved the way to a 39-16 win for the visitors.
