The game at Widnes Vikings’ Stobart Stadium is a sell out with 12,975 tickets sold.
Wigan coach Brian Noble has named O’Loughlin and Bailey in the squad for Saturday’s semi final against Warrington Wolves, although Noble says O’Loughlin will only play if fully fit.
“His chances are pretty good,” said the coach. “He’ll only play if he’s fully fit but he’s taking part in training and we’ll make a decision on Thursday or Friday.
“He did a bit of training last week and he’s progressing well. He’s a consummate professional and has due diligence in relation to his rehab.
“He’s important to us and so it’s important that we give him the best opportunity to play. He’s a world-class player.”
The Warriors will be without Darrell Goulding who is sidelined with a dislocated shoulder.
Warrington coach Tony Smith said that Riley would be an adequate replacement for Carney after he was restored to the Wolves starting line up.
“Chris was probably a bit unlucky to miss out last week,” said the England boss. “He handled it professionally. He’s ready to go and ready to do his best this week.”
Wigan last reached the final in 2002 when they lost to St Helens at Cardiff, while their last cup win was in 2002 when the beat the Saints 21-12 in Edinburgh.
Wigan and Warrington met at the semi-final stage in 2004; that game was also at Widnes, and the Warriors wn 30-18.
