Cardiff Blues wing Owen Lane has been called into Wales' World Cup squad as replacement for injured Josh Navidi.
The Wales back-row forward was ruled out after a hamstring injury during the team's quarter-final victory over France on Sunday.
Navidi said he has been ''humbled'' by the message of support he has received.
Owen Lane made his Test debut during Wales' World Cup warm-up games over the summer.
Speaking at a press conference, Wales defence coach Shaun Edwards said Lane has ''huge potential.''
''We were very impressed with him over the summer,'' Edwards said.
''He's got some great banter as well. Sometimes you need that after being away from home so long.''
