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.
Henry Purdy, a first half replacement for Charlie Sharples, was amongst the try scorers in the 64-19 victory over Aviron Bayonnais on Saturday evening and told GRTV that it was a professional performance, one the team are happy with.
Gloucester's win in Treviso last week means that they need a bonus point win against Bayonne on Saturday evening to secure a home quarter-final (kick off 8pm), but Tim Taylor wants the team to focus on the performance first and foremost.
Billy Burns and Man of the Match Richard Hibbard spoke to GRTV after the 41-0 win in Treviso, on a day when preparations weren't ideal. They felt the team's attitude was key and also praised the travelling support.
Following the conclusion of the Stade Francais vs Harlequins game today, round six is complete and the quarter-finalists in the European Rugby Challenge Cup are now known with Gloucester set to welcome the Cardiff Blues to Kingsholm.
Knowing a bonus point win would secure a home quarter-final, Gloucester completed their European mission in some style on Saturday evening, sweeping aside a spirited but outgunned Aviron Bayonnais scoring 10 tries on their way to a 64-19 victory.
