Mignoni is unfit for quarterfinals

MARSEILLE, France -- France scrum-half Pierre Mignoni will miss the World Cup quarterfinal against New Zealand because of a thigh injury, the team announced on Monday.

Mignoni was hurt during the 64-7 win against Georgia on Sunday, pulling up midway through the first half as he chased the ball.

His place goes to Jean-Baptiste Elissalde, who is likely to start in Saturday's match in Cardiff.

Tight head prop Jannie Du Plessis has been added to South Africa's World Cup squad as a replacement for injured BJ Botha.

Du Plessis is expected to arrive in France on Wednesday or Thursday.

Botha suffered suspected knee ligament damage in Sunday's 64-15 win over the United States.

The Springboks play Fiji in the quarter-finals on Sunday, in Marseille.

Australia have added Morgan Turinui to their squad to play England. He will replace injured forward David Lyons, who broke a leg in the 37-6 Pool B win over Canada in Bordeaux.

Centre Turinui, a former Wallabies vice-captain, played the last of his 20 Tests in 2005.

Wales flanker Martyn Williams has announced his retirement as an international following the World Cup campaign defeat by Fiji.

"I just think it's the right time to step aside," said the 32-year-old who won 76 caps in his 11-year international career.

Williams, who made his debut in 1996, captained Wales five times and was in the team which won the Grand Slam in 1995. E-mail to a friend
