SPEEDSTER Rio Dyer’s World Rugby U20 Championship is over because of a shoulder injury with Dragons teammate Joe Goodchild replacing him in the Wales side to face New Zealand tomorrow (kick-off 3.30pm).

Dyer was injured in the opening exchanges of Wednesday’s 26-21 win against Australia when the rapid 18-year-old from Rogerstone went up for a high ball.

He was replaced by Goodchild and the winger from Garndiffaith went over for the Welsh youngsters’ second try against the Junior Wallabies.

Head coach Geraint Lewis said: "We're very disappointed to lose Rio, given all the threats he poses on the pitch, and wish him a speedy recovery.

“Joe's got a chance to step in now - something he did against Australia with great confidence."

Goodchild is the only change to the XV for the clash against the formidable Baby Blacks.

Fellow Dragons Max Williams and Taine Basham start at lock and number eight respectively while flanker Lennon Greggains is among the replacements.

"We were delighted to come away with a good win that was full of positives against Australia but we know New Zealand will be another step up for us,” said Lewis.

“Thankfully we've got the desire and hunger to improve within this squad. The players are excited about pitching themselves against the best players in the world at this level, and there's been a real buzz around the camp for tomorrow's game."
