DRAGONS boss Bernard Jackman believes Aaron Wainwright can force his way into Wales' summer plans by finishing a breakthrough season with a big display at Judgement Day.

The Rodney Parade region bring an end to a challenging campaign when they lock horns with the Scarlets at the Principality Stadium double-header tomorrow (kick-off 3.05pm).

The Dragons have endured a tough season that has featured just two Guinness PRO14 successes, both in September, but back row forward Wainwright has consistently shined brightly amid the gloom.

The 20-year-old from Bassaleg has played in 24 of 25 games since making his professional debut at the Arms Park against Cardiff Blues in October.

Wainwright's dynamic displays caught the eye of Wales forwards coach Robin McBryde, who said in the January that he had been impressed with his ball carrying.

The national side are blessed with a glut of back row forwards but Jackman believes his young prospect would thrive if given a chance to tour for the June Tests with South Africa and Argentina while others are rested.

"Aaron has had a hell of a season," said the former Ireland hooker. "For a guy that didn't make Wales Under-20s last year he has been outstanding.

"I know that the Wales back row is incredibly competitive but if they don't take some of the senior guys then he is someone that certainly could step up."

Judgement Day is seen as a Welsh trial with international hopefuls getting the chance to stake their claim on the big stage.

Internationals Elliot Dee and Hallam Amos will be looking to cement leading roles for the summer tour while Jackman is hopeful that some of his youngsters impress.

"Wales have a lot of good wings, but in terms of current form Jared Rosser has scored seven tries and is getting better game on game," said the head coach about his speedster, who is fresh from a hat-trick against Zebre.

"He started well, had a little bit of a dip and has come through that, which is how most young fellas' careers go. He is coming out of the other side of that.

"Harri Keddie is also a very good player who we think a lot of but has had an interrupted season with an operation on his shoulder."

Back row forward Keddie is has passed his return to play protocols to feature against the champions after a head injury in the loss to Benetton but the Dragons are without Lewis Evans (neck) and captain and lock Cory Hill is a big doubt (toe).

They are boosted by the return of Amos, who is back from Commonwealth Games duty to slot in at 15 with former Springbok Zane Kirchner likely to move to midfield.

"As an attacking threat Hallam gives us the most x-factor," said Jackman. "He has a good left foot and when you have some like him, you want them involved as much as possible and as a full-back he will get more touches than on the left wing."

The Dragons, who haven't won a league derby since Boxing Day, 2014, name their team at midday.
