Ireland are heading south to Fukuoka today as they begin preparations for their final World Cup Pool A clash with Samoa on Saturday week.

Yesterday's bonus point victory over Russia leaves quarter-final qualification in their own hands.

There were a couple of injury concerns to come out of the game, with Jordi Murphy appearing to leave the pitch in some discomfort with an apparent rib injury.

Speaking with RTÉ Sport's Michael Corcoran, forwards coach Greg Feek explained that they should have a better idea of Murphy's chances of playing again in the tournament after a scan today.

"Jordi, it's in his rib, you saw on TV that he's in quite a bit of pain," said Feek.

"He's going to get scanned today (Friday); there was a bit of a delay sorting it out after the game yesterday, so he'll get that sorted and we'll know more.

"In terms of managing a rib, obviously with rugby being a contact sport, in this team we're pretty used to it. We have some good systems, and it's just dependent on the degree of that (injury), and we'll go from there."

The other concern lies with Joey Carbery, who was withdrawn from the squad before kick-off.

"It was precautionary, obviously with getting a stamp," insisted Feek.

"I also think at this time of the campaign there's no point taking risks. We'll probably know more about him later today, or maybe tomorrow, but it's not all bad news there."
