Wales will be without Josh Navidi for the remainder of the World Cup after the back row forward suffered a hamstring injury in their narrow quarter-final victory over France on Sunday.
It is a significant blow for the Principality as they prepare to face South Africa in their first semi-final in eight years in Yokohama on Sunday.
The 28-year-old Cardiff Blues number eight has been a key figure in Warren Gatland’s plans for this World Cup, keeping former Lion Ross Moriarty out of the starting fifteen.
However, he suffered a hamstring injury mid-way through the first half of the 20-19 win over France, with Moriarty coming on to score the winning try just minutes from full-time.
Wales head coach Warren Gatland has indicated that he will call up a replacement, but refused to indicate whether it would a back row forward amid strong speculation that he is keen to bolster his back division.
Wales hope to have centre Jonathan Davies back for the semi-final after missing Sunday’s game with a knee injury.
