BRAD Dwyer could prove the unlikely key to Warrington Wolves unlocking Challenge Cup opponents Dewsbury Rams tomorrow, Friday.

Tony Smith has called the hooker back from a loan spell at London Broncos for one month because of injury to Daryl Clark, who is expected to return at Salford next Friday.

But with Dwyer having faced the Championship outfit three times already this campaign, Wolves’ head of coaching and rugby has sought the 22-year-old’s experience.

“Richard Agar played a lot of his career there, Anthony England knows it well and Brad Dwyer being back is convenient,” said Smith.

“Brad’s played them three times this year. He knows them really well and played well against them. Hopefully he can give us some insight.

“We understand their strengths and have hopefully found a few weaknesses we can exploit as well.”

And Academy graduate Dwyer has impressed in the capital this season.

“Reports from the officials believe he’s been if not their best player then very close to it each week,” explained Smith.

“The games that I’ve seen I can’t argue with that. He’s been very prominent and even in some of their defeats he’s been a stand out.

“We’ve got this window of a month that we could bring him back.

“Daryl having the injury at the moment left us vulnerable, so we thought it was time and that way we can make sure we’re not causing further injuries to other people.”

Stefan Ratchford is rested, while Toby King is wearing a protective boot after suffering syndesmosis in his ankle against Hull FC that could sideline him for a month.

Matty Russell is hoping to be back within two weeks.

As for Friday’s opponents, Smith will not be underestimating a side bidding to make the ‘middle eight’.

“We’re not under any illusions it’s going to be an easy game – it’s going to be tough – but I’m expecting our boys to get out there and over a period of 80 minutes wear a team like Dewsbury down,” he added.

“We’ve done plenty of homework on them and they’re a decent team. They’ve been fighting for the top four all year.

“On a small ground it's going to be tough. Their pitch is 62 metres wide – it’s narrow and short.

“So a small ground, small dressing sheds, slopes, conditions local teams know and play well, these are things we have to take into account.

“They’ve got a huge squad in numbers. They’ve got many experienced players who are very experienced in Super League as well as in good Championship teams.

“It’s about going there, being professional and doing a good job. That’s what we’re intending to do.”
