Mermoz, who had taken over at inside centre from the veteran Jauzion, was ruled out of the trip to Dublin after injuring his left shoulder in France’s 34-21 home victory over Scotland.
The injury has forced coach Marc Lièvremont into making yet another change to his back line — the 18th since he took over Les Bleus And he admitted yesterday it was unlikely Mermoz would return to full fitness before the end of the tournament.
“Once again I will not be able to field the same backs line-up for two successive matches,” said Lièvremont.
“I think it would be complicated,” the coach added of Mermoz chances of staging a recovery in time to feature in the Six Nations.
“We’re not going to talk about the nature of his injury too much and we’ll leave the treatment to his club (Perpignan).” Jauzion has amassed 68 international caps, scoring 20 tries, since making his debut in France’s 32-23 victory over South Africa in Johannesburg in 2001.
The 32-year-old, who was part of Les Bleus’ Grand Slam winning sides in 2002 and 2004, last appeared in France’s 16-59 demolition by Australia at the Stade de France in November.
Scrum half Morgan Parra has urged his team mates not to get carried away following the Grand Slam holders’ 34-21 victory over Scotland.
Parra was delighted with the performance against the Scots, which put to bed memories of their 16-59 beating they received at the hands of Australia at the Stade de France back in November.
But with a trip to the new Aviva Stadium on the horizon, Parra insisted that they would be no let up in training during the week.
“We’ll definitely have a few things to work on during the week,” said Parra.
“We’ll have to look at our defence and a few other things.” After Ireland’s close shave in Rome, Parra said he expected Brian O’Driscoll’s men to be an altogether different prospect at their new Lansdowne Road venue this weekend.
“It’s going to be tough, that’s for sure,” he added. “It’ll be another stadium with another atmosphere and facing up to this Irish team. So it’s going to be interesting to say the least.
“We’ll do our best to get the most out of the match though. We’ll have to start looking towards the game quickly because the time will fly during the week.
“We know a lot of the Irish players from the Heineken Cup so we know all about the speed of their play, their technical ability, how they defend and so on.
“It’s true that from that we have a little better understanding of their style of play so maybe we can anticipate a little more what they will try to do. But they’re a great team so it’ll be really difficult to win over there.”
