CARDIFF Blues wing Owen Lane has been called into Wales's World Cup squad as replacement for injured back row forward Josh Navidi.

The 21-year-old made his Test debut during Wales's World Cup warm-up games, scoring a try against Ireland in Cardiff.

He is now joining the Wales squad in Tokyo ahead of Sunday's semi-final against South Africa in Yokohama (kick-off 9am).

Lane can also play centre and was selected ahead of Scott Williams as Warren Gatland looks to ensure he has cover for his back line.

Wales are well-stocked in the back row but Jonathan Davies is on the comeback trail from a knee injury and his first-choice midfield partner Hadleigh Parkes has been playing with a broken bone in his hand.

Lane is unlikely to face the Boks, as George North would be another midfield option, but has been welcomed into camp.

"He's a great character, a very good player with huge potential," said defence coach Shaun Edwards. "We were very impressed with him in the summer."

Wales will miss the presence of strong back rower Navidi.

The Cardiff Blues forward suffered a hamstring injury in the first half of the quarter-final win against France.

"He's been one of our go-to players over the last two years, everyone is gutted for Josh," said Edwards.

"He's one of our best defensive players and someone has to step up."

Dragons number eight Ross Moriarty is in pole position to be that someone after coming off the bench against Les Bleus.

He was yellow-carded for a high tackle but redeemed himself with the match-winning try at the death.

Aaron Shingler and James Davies of the Scarlets are the other back row options.
