Ireland have been dealt a blow with the news that Jared Payne could miss Sunday's World Cup clash with Ireland on Sunday.

A bruised foot forced the Ulster centre to sit out of Wednesday's training session as Joe Schmidt continues to prepare his side for the Pool D game at the Olympic Stadium.

"Jared Payne didn't train today. He's just got a bit of a bruise on his foot, he didn't train, so we'll see how he goes for the rest of the week," scrum coach Greg Feek told reporters.

Ireland are also sweating on the fitness of Rob Kearney as he is still battling with a gluteal strain.

Schmidt's men will book their quarter-final spot with a victory in the capital.
