PLAYMAKER Sam Davies has been challenged to consistently hit the heights for the Dragons in order to force his way back into the Wales matchday squad.

The 26-year-old was called up to Wayne Pivac's Six Nations squad last week after Dan Biggar suffered a knee injury while playing for Northampton.

With Gareth Anscombe, Rhys Patchell and Owen Williams sidelined, Davies was brought in by Wales but wasn't needed for the clash against England.

Biggar impressed at fly-half and Jarrod Evans was an unused replacement, with the duo set to go again in the tournament finale against Scotland in Cardiff on Saturday.

Davies was part of the pre-match preparations at Twickenham and will once again be next in line for the Principality Stadium clash.

That is reward for the left-footer's encouraging start to life at Rodney Parade after moving from the Ospreys last summer.

Davies, who came off the bench in the November fixture against the Barbarians, has called the shots for the Dragons and kicked them to victory against Worcester, the Scarlets, Ospreys and Cheetahs.

The 2013 World Rugby young player of the year turned down offers from outside of Wales in favour of the Rodney Parade region in a bid to add to his eight caps.

Consistency is key to Davies featuring for the first time since facing Samoa in the summer of 2017, according to Wales skills coach Neil Jenkins.

"Sam has to keep improving and keep getting better," said the legendary former fly-half/full-back, who is top of Wales' all-time points chart with 1,049.

"He is a very good rugby player, we know that, but is he at the form of a couple of years ago? Maybe, maybe not, but if he can consistently play well week in, week out (then he will push for selection).

"I know that he is a very, very good kicker and that could be a big part for us going forward. It's just consistency of form for Sam and playing well week in, week out for the Dragons to keep putting his hand up. That's the key.

"Sam knows that he is in the mix and in the frame. I'd certainly be very happy to be called up and included in the squad, so he is a very talented player and just needs to keep showing that."

Wales will be without lock Jake Ball for 12 weeks after he suffered a shoulder injury against England but report no other injury worries.

Dragons tighthead Leon Brown suffered a shoulder stinger in the build-up to Manu Tuilagi's clinching try at Twickenham but finished the game.

He replaced Dillon Lewis (ankle) in the second half but Wales expect to have both props in contention for the Scotland clash, with Sale's WillGriff John the other tighthead option in the squad.

Dragons forward Ross Moriarty started at blindside gainst England while Aaron Wainwright missed out because of back row competition.

Hooker Elliot Dee and lock Cory Hill have been hindered by calf and hamstring injuries respectively while promising flanker Taine Basham is covering the back row and wing Ashton Hewitt has been training with the Test team, although he isn't an official member of the Six Nations squad.

Head coach Wayne Pivac names his team at midday on Thursday.
