DRAGONS flanker Lennon Greggains returns to the Wales XV for tomorrow's World Rugby U20 Championship clash with New Zealand (kick-off 2.30pm).

The 20-year-old from Newport has been sidelined since suffering a shoulder injury in the tournament opener against Argentina.

The influential back row forward returns for the daunting clash with the Baby Blacks in the play-offs, with the winners going on to play for fifth place against either England or Ireland and the losers facing off for seventh.

Head coach Gareth Williams has freshened up his side for the fixture after last week's topsy-turvy encounter with Fiji, in which the Welsh youngsters stretched away in the final quarter for a six-try 44-28 success.

Dragons scrum-half Dafydd Buckland keeps his place, as does his regional teammate Deon Smith after switching wings to the right with Scarlets speedster Ryan Conbeer returning down the left. Cardiff Blues centre Max Llewellyn returns to the XV.

The props are changed either side of captain and hooker Dewi Lake, Kemsley Mathias coming in for Dragons loosehead Tom Devine and Ben Warren swapping with Caldicot tighthead Nick English of Bristol Bears.

Morgan Jones comes in for Dragons lock Ed Scragg while Greggains joins forces with the impressive Leicester openside Tommy Reffell and in-form number eight Jac Morgan.

New Zealand won their first two games with bonus points and are the tournament's leading try scorers but failed to make the semi-finals after being pointless in their defeat to South Africa.

Williams is relishing the chance to see his prospects, who beat hosts Argentina before seeing their own last-four hopes dashed by France, go up against a formidable side.

"We've always emphasised how important the squad of 28 is, and this is getting more and more evident the longer we go in to this competition," said Williams.

"Playing New Zealand is a great test for us, and a great fixture to be preparing for. They are rightly regarded as one of the best teams in the world at this age group.

"We don't always get the opportunity to play southern hemisphere teams so this is a big challenge for us but one we have prepared well for."

Scragg and Devine are joined among the replacements by Dragons teammates wing Rio Dyer and hooker Will Griffiths.
