The Great Britain international is recovering well from a shoulder injury and is in line to face the Challenge Cup finalists.
And in a boost, coach Brian Noble is hoping to welcome back three other first-team stars returning from injury or illness.

Phil Bailey, Darrell Goulding and Pat Richards are set to figure in the Warriors' final match of the regular season.
O'Loughlin has to undergo another scan before he is cleared to play. But he said: "It's not definite, but it's looking good and the recovery is going well.

"I'll have to wait until next week to find out for definite, but fingers crossed."
Gareth Hock is still absent due to suspension.

Meanwhile, Wigan's plans for 2009 are nearing completion. The club are poised to announce that Australian utility Cameron Phelps and full-back Richard Mathers have agreed new deals.

Phelps was out of contract, while Wigan had an option on whether to retain Mathers.
The Warriors are also handing forward Harrison Hansen an extension on his current deal which expires next year.

Noble is likely to bring in one more overseas star after discovering that Kiwi scrum-half Thomas Leuluai will not count on the overseas quota.

Leuluai moved to Super League before he turned 21, effectively making him a homegrown player.

With no game this weekend because of the Challenge Cup Final, Noble reports that they have trained hard in preparation for next Friday's showdown at St Helens.

Saints have a superior for-and-against of 51 over second-placed Leeds but are unlikely to run the risk of sacrificing the league leaders' shield – and a home game in the play-offs – particularly as the in-form Rhinos have a relatively easy match against Wakefield.

Noble added: "The one team we haven't performed against this year is St Helens, and we want to address that."
