World Cup digest: Australia suffer Martin Boyle blow

Australia winger Martin Boyle was ruled out of the World Cup by a knee injury on Sunday, two days before the Socceroos open their campaign against world champions France.

The Scottish-born forward, who had been an injury doubt since the squad arrived in Qatar after suffering the injury playing for his club Hibernian, will be replaced by Marco Tilio.

"We all feel for Martin and it is a cruel blow for him on the eve of the World Cup," coach Graham Arnold said in a statement.

"He has been an integral part of our journey to get to Qatar and we thank him for everything he has given the Socceroos during this campaign.

"He will be back and we can't wait to see him in the green and gold again next year."

Tilio, a 21-year-old winger, is in Qatar having arrived on Tuesday as precautionary cover for Boyle.

"Marco has done everything that has been asked of him to be ready for this tournament," Arnold said.

"He was an important member of our Tokyo 2020 Olympic team ... and he is familiar with the national team set up and we are looking forward to what he can bring to our squad for the tournament." Australia also play Denmark and Tunisia in Group D.

France coach Didier Deschamps has decided not to replace injured striker Karim Benzema in his squad, leaving the reigning champions with 25 players for their title defence.

Benzema trained with the squad for the first time since arriving in Qatar on Saturday but was forced to leave the session early with a thigh injury and scans ruled him out of the tournament.

Asked on Sunday by TeleFoot whether he would replace the Ballon d'Or winner in his squad, Deschamps said "No".

"This is a quality group," he added. "In everything they do, both on and off the pitch, they are united. I have confidence in them."
