Warriors wing Melani Nanai will miss the rest of the season having undergone surgery for a shoulder injury.
Nanai joined Warriors from Super Rugby side Blues last summer and made eight appearances – all starts – before he suffered the shoulder injury in December.
The former Samoa Under-20s international has now had an operation to repair a torn muscle and remove a piece of floating bone.
Nanai’s fellow wing Tom Howe also faces a spell on the sidelines because of a calf muscle injury.
It was initially feared that Howe would be out of action for around eight weeks but his latest scans were more encouraging and he is now expected to be out for around half that time.
