GLOUCESTER hooker Mefin Davies has been diagnosed with a damaged vein in his left calf following the injury he picked up against Saracens almost a fortnight ago.
The Welsh international hooker will be monitored over the next fortnight by Gloucester's medical team but there is no indication yet on a potential comeback date.
Davies has featured in six of Gloucester's seven Guinness Premiership games so far this season.
Head coach Dean Ryan said: "We recognise Mefin is an integral part of our squad but we have made it clear this season we are not prepared to rush players back from injury and he will have all the support required to recover fully.
"The timing is very unfortunate for Mefin but it will provide opportunities for other players within our squad to stake their claim for a starting spot."
Gloucester will field a reshuffled side against the Ospreys in the LV= Cup this weekend, but Backs & Attack Coach Nick Walshe stressed that it's a great opportunity for everyone on duty on Saturday and that maintaining the recent winning run is very important.
Skipper Billy Twelvetrees told GRTV after the win in Brive that the game could have been a tough one to get up for, but that his Gloucester team mates did themselves proud on the night and got a big result.
Reflecting on the 31-20 victory in Brive on Thursday evening, Director of Rugby David Humphreys said that clinching a home European Rugby Challenge Cup quarter-final was the overall aim and duly achieved.
Gloucester may have already clinched a home European Rugby Challenge Cup quarter-final, but Director of Rugby David Humphreys wants his side to finish the pool stages on a winning note in Brive on Thursday evening.
Gloucester Rugby and the Ospreys shared seven tries and 57 points in the LV= Cup at Kingsholm on Saturday. The Cherry and Whites came out on top and the club photographer captured the best of the action.
