Wigan�s new signing Luke Davico is facing an uncertain future after hospital scans confirmed a tear to his pectoral muscle.
The former Canberra Raiders prop forward, who was out for six months with the same injury last season, suffered the latest blow in the Warriors� friendly match at Salford on Tuesday.
�It�s bad news,� confirmed coach Denis Betts. �I feel for the lad more than anything else. �He had settled in really well and was enjoying his time here. It�s not a nice way to start your new career.
�He�s had some scans and seen the specialist and we�re just waiting on some feedback.�
Wigan are still reeling from the shock of losing skipper Andy Farrell for four months with a knee injury but they will welcome back full-back Kris Radlinski from a back injury for Sunday�s friendly against London Broncos at Orrell.
Radlinski pulled out of Great Britain�s squad for the Tri-Nations Series after succumbing to a lower back injury but has completed a period of rehabilitation and will lead the side in Farrell�s absence.
The Warriors will also give first appearances to new signings Jerry Seuseu and David Vaealiki against the Broncos, who have New Zealand Test half-back Thomas Leuluai returning from injury.
