France out-half Romain Ntamack ruled out of World Cup with knee injury

France out-half Romain Ntamack has been ruled out of the World Cup due to a knee injury, the French Rugby Federation has confirmed.

Ntamack had a knee scan on Monday morning after limping off the field in a Saturday warm-up Test game against Scotland.

"Ntamack was hit in the left knee and had to leave the field," said the FFR on their website.

"Imaging this morning diagnosed a rupture of the anterior cruciate ligament. As a result, Romain Ntamack will be forfeited for the World Cup."

France also lost prop forward Cyril Baille to a calf injury as they scraped a 30-27 victory over the Scots at the Stade Geoffroy-Guichard.

The Toulouse man will be out for five to six weeks.

France are in Pool A of the World Cup and face New Zealand, Uruguay, Namibia and Italy. The top two teams will progress to the quarter-finals where they will face the winners and runners-up from Pool B, which contains Ireland, South Africa, Scotland, Tonga and Romania.

"It remains a preparation match, with a different team from last weekend, who played together again for the first time since the end of March," head coach Fabien Galthie said of the win over Scotland.

"The Scots have a month and a half of preparation more than us because they finished their Championship in mid-May. Our goal is to continue preparing for a month and, even during the pool phase of the World Cup, there will be work to ramp up."

It was the second successive Saturday that France played Scotland, and they had put out a second-string side at Murrayfield last weekend and lost 25-21.
