Cardiff Blues flanker Josh Navidi has been ruled out for the majority of a Six Nations after suffering a re-occurrence of the hamstring injury he picked up at the World Cup.
The 29-year-old limped out of the quarter-final against France in Japan, an injury that kept him sidelined until Boxing Day’s derby against the Dragons at the Arms Park, and he will now be in the stands for at least four more weeks after doing his hamstring again in training with the Wales squad.
It is a big blow for Wayne Pivac who has lost the best flanker over the ball named in his initial Six Nations squad, with Aaron Wainwright and Aaron Shingler set to battle it out for the final spot in the back row alongside Justin Tipuric and Taulupe Faletau over the next few weeks.
Navidi is the second Cardiff Blues player to pick up an injury in the pre-Six Nations training camp, with Owen Lane suffering a ‘significant’ hamstring injury last week that is likely to keep him out for the rest of the season.
No squad replacements have been called up for either player as things stand.
