Black Friday as World Cup casualties mount

Rio de Janeiro (AFP) - France star Franck Ribery was ruled out of the World Cup as fears of burnout mounted over a lengthening list of players who will miss the tournament through injury.

"We had stepped up (Ribery's) level of work this week and it was in a training session this morning, before even he could join team training, which involved him running and stepping up his routine that he pulled up with a sharp pain in his back," Deschamps said.

"We had him undergo examinations which unfortunately confirmed that he had aggravated his back problem and there was no question of him being able to either train nor play."

Ribery's withdrawal deprives France of their prime attacking focal point, who a year ago cemented his position as one of world football's top talents.

Later Friday, Germany were also given a huge fright when midfielder Marco Reus hobbled out of his team's 6-1 drubbing of Armenia in Mainz.

The Borussia Dortmund star -- a certain starter in the German line-up -- limped off in agony after the injury.

"I don't know yet what it is, we have to wait," said concerned Germany coach Joachim Loew.

"You could see the foot was swollen and I hope it's not a ligament (injury)."

With Portugal star Cristiano Ronaldo also struggling to be fit in time for his country's Group G opener with the Germans on June 16, coach Paulo Bento reflected on the toll that a gruelling European season takes on the sport's top players.

Even though Ribery and Reus play in the Bundesliga, which allows players a substantial mid-season break, Bento questioned whether the physical demands placed on footballers was now too great.

"For a few years it's normal that players arrive at the World Cup or European Championships tired -- physically and emotionally -- because they have long, long seasons, mainly in Europe," Bento said.

"Things are not getting any better. The players are being forced to play more matches and recovery time is getting less and less.

"I don't think we (the football authorities) are going in the right direction."

France and Germany were not the only teams struggling with injury concerns on Friday.
