Flanker Anthony Jelonch was named in host nation France's Rugby World Cup squad by head coach Fabien Galthie on Monday despite suffering from a serious knee injury.
Jelonch, 27, made the last of his 25 Test appearances in February when he ruptured an anterior cruciate ligament in the Six Nations victory over Scotland.

Les Bleus open the World Cup by facing three-time winners New Zealand at the Stade de France in Paris on September 8.
They then play Uruguay six days later, Namibia on September 21 and end their Pool A campaign against Italy on October 6.
"Anthony has worked a lot to get back to where he is now," Galthie told TF1.
"He's not fit now but we think he will be back to his best by mid-September."
Jelonch's club teammate, prop Cyril Baille, is also included but is suffering from a calf issue. Galthie also expects him to return by the middle of next month.
Last week, France suffered a setback when first-choice fly-half Romain Ntamack was ruled out of the tournament with a serious knee injury.

Youngster Louis Bielle-Biarrey as well as two-time Champions Cup winner Paul Boudehent also get the nod, despite only making their Test debuts earlier this month.
