PAUL JACKSON will hope for a good week on the training field in a bid to win back a first-team spot.

The 28-year-old prop, pictured right, missed the home clash with Warrington nine days ago after suffering a back strain in training.

He was fit to return against Wakefield on Sunday, but missed out to fellow front-rower Darrell Griffin, who produced a rock-solid display against his former club.

That could make Jackson’s chances of featuring in Saturday’s clash against Harlequins at The Stoop tough.

But head coach Jon Sharp has made it clear selection for the capital clash will not be decided until he has seen how everyone shapes up in training.

“Our win at Wakefield on Sunday was down to a tremendous team effort,” said Sharp.

“And with all 17 having come through that match free from injury, they have to be in with a chance of keeping their places against Harlequins.

“But I know the likes of Paul might have something to say about that.

“He was definitely in the frame for the game against Warrington the other week and was very unlucky not to be included.

“It’s now up to him – and Stuart Jones, for that matter, who was rested last weekend – to show me he should win back his place on Saturday by continuing to work hard on the training ground.”
