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 Rugby will take on Wasps on Sunday in their first ever visit in the Aviva Premiership to the Ricoh Arena. Speaking to the local media today, Director of Rugby David Humphreys previewed the game as well as giving an update on the injured Henry Trinder.
Following the 48-10 Aviva Premiership win over London Welsh on Saturday, Dan Murphy praised his team mates for battling right up to the very last minute in difficult conditions and maintaining the momentum that the team have built in 2015.
Henry Purdy scored two memorable tries against London Welsh at Kingsholm on Saturday, and attributed the first one to hard work on the training ground before describing how much he's enjoying playing his rugby alongside friends like Callum Braley.
Gloucester dominated for long periods against Wasps at the Ricoh Stadium on Sunday afternoon but were made to pay the price for defensive lapses and a number of key refereeing decisions not going their way in a 32-21 defeat.
A number of the Gloucester Rugby squad this week benefitted from an initiative organised by Circle 2 Success (C2S) and the Rugby Players Association (RPA) to help players develop their business planning skills.
