SAINTS duo Martin Gleeson and Sean Long are available for selection despite the investigation into the betting allegations - but both may still miss Sunday's Challenge Cup semi-final through injury.

Huddersfield chairman Ralph Rimmer had called for the pair to be suspended until the investigation is completed - something Saints and the RFL have both rejected.

But on Tuesday Saints' coach Ian Millward said both players were a concern ahead of Sunday's crunch clash at Warrington.

He said: "Sean has missed the last two games and not trained with us this week, so he is a worry as is Martin, who is troubled with his hand.

"I think Martin has a better chance.

"With Dominic Feaunati and Jon Wilkin suspended it leaves us a little short, but the guys who came in on Friday performed well."

Millward has the option of switching Jason Hooper or Lee Gilmour to centre, with Mick Higham or Carl Forber, who made an impressive debut last week, able to cover scrum half.

Huddersfield, now coached by Saints' former assistant Jon Sharp, have started the season well and will be a tough nut to crack.

The Giants have a rough, abrasive pack which lays the platform for equally robust halves Paul March and Brandon Costin to work off.

They also have bags of pace in Marcus St Hilaire, Hefin O'Hare, Stuart Donlan and Paul Reilly.

Saints' full back Paul Wellens, who has started the season on top form, has identified his duel with opposite number Reilly as a key battle.

He said: "I think Reilly has been playing well for two seasons, but only now getting the recognition. He is a very strong player, a great runner of the ball and defensively very sound.

"Huddersfield have a very good team spirit and they work really hard for each other. And since Jon Sharp has gone there they are playing a lot more rugby and where they are in the Super League is a true reflection of that.

"They like to play the game tough and make no secret of that. We are aware this will be a very tough game and our pack will have to rise to the challenge."

Wellens grabbed the last minute winner in the last clash between the sides last term.

"We snatched victory from the jaws of defeat and should never have won that game as they had dominated for 80 minutes, which shows how good they are. Hopefully it won't be as close this weekend.

"As players you don't think of Cardiff - but it is there as motivation for us especially as we missed out last year," Wellens said.
