GLOUCESTER'S French hooker Olivier Azam will be out of action for up to 12 weeks following an operation on his injured left shoulder.
The Kingsholm number two will spend the next four weeks in a sling following surgery to repair labral damage before starting his rehabilitation course.
The injury is almost identical to the one he suffered last season to his right shoulder and he is likely to be out of action until the end of February.
Azam suffered the set-back in October but had appeared to be close to a potential return when he resumed contact training before Gloucester's Guinness Premiership trip to London Irish last month.
But the injury, which affects the shoulder's stability, did not settle down and required a subsequent operation. Gloucester's head coach Dean Ryan told www.gloucesterrugby.co.uk. "Everyone at the club is obviously very disappointed for Olivier, particularly after the problems he suffered last year.
"To sustained another serious injury so quickly is disappointing for him and to us because we will miss the huge contribution he makes to the team.
"All we can do now is wish him a speedy recovery so he his back with us as soon as possible."
Azam, who has made four Premiership appearances this season, has scored 12 tries in the 57 games he has played for Gloucester in two spells.
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.
