WIDNES are counting the cost of Friday's 34-18 Super League defeat to the Giants.
Experienced Vikings full-back Gary Connolly could be out of action for up to six weeks with a broken thumb.
Former Great Britain star Connolly, who joined the Vikings from Wigan in the close season, had featured in the club's opening five matches.
The news is a further blow for coach Frank Endacott's side, who have already lost captain Shane Millard with a broken jaw.
And stand-off Owen Craigie is also a major doubt for the Vikings' trip to London Broncos on Sunday after he was forced to leave the field against the Giants after 34 minutes with a knee injury.
But there's better injury news for Wigan, who expect to have Great Britain winger Brian Carney back for Friday's derby with Leigh.
The Irishman has missed all of Warriors' five matches so far because of complications caused by the metal plates inserted in the ankle he broke 12 months ago.
