WARRIORS pair Duncan Weir and Sam Lewis will be both be side-lined for around 12 weeks with shoulder injuries that will require surgery.
Both sustained the injuries against Leicester Tigers two weeks ago with Scotland international fly-half Weir suffering a grade three tear in his acromioclavicular joint and openside flanker Lewis a grade four tear in his same joint.
Warriors hope that fly-half Billy Searle will return to action within two to three weeks having missed the Gallagher Premiership matches against Leicester and Wasps because of a gashed thigh muscle which he sustained against Exeter Chiefs three weeks ago.
Hooker Matt Moulds is on course for a return to action in the middle of next month after almost a year out with a foot injury.
Moulds underwent surgery to repair and stabilise an existing injury last summer but further complications have delayed his comeback.
