Wigan's bid to reach the Challenge Cup final has been boosted by the return to fitness of Australian star Phil Bailey and captain Sean O'Loughlin ahead of Saturday's semi-final against Warrington.

Bailey is back after missing Wigan's last two matches with a leg injury, while loose forward O'Loughlin had been sidelined for the Warriors' last four games with a knee injury.

"Sean's chances are pretty good," Wigan coach Brian Noble said on Tuesday.

"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."

Wigan have been led for the last two weeks by former Warrington centre Martin Gleeson, who added: "Sean's a big figure in our team and it would give us a boost if he's back."
