Australia's Matthew Lappin is facing the prospect of missing Sunday's first Test at Croke Park.

The Carlton player would be a significant loss. One of the four All-Australian players who made the trip, he also played well for nine points in Wednesday's practice match against a Dublin selection, during which he picked up a knock.

"Matthew has a slight quad injury and is more doubtful than positive for the test," said AFL PRO Patrick Keane.

"We'll see him at training before making a decision, but he's a worry."

Sydney's Jude Bolton and Geelong's Joel Corey are also bothered with a hamstring and ankle injury respectively, but are expected to pull through.

Bolton's club-mate Jared Crouch, the remaining player who sustained an injury on Wednesday, will definitely play.

Yesterday was a rest day for the Australians. "We had a pool session at 8.30 this morning," said Keane. "After that the guys were free to play golf or go sightseeing."

The profile of the international series is growing in Australia, he said. "This is far and away our biggest media contingent. Twelve have travelled, and that's the biggest symbol of the growing interest. People are arguing about whether this is the best team. In the beginning they didn't talk about it at all."

Meanwhile, Ireland manager Pete McGrath reports no late injuries going into today's final training session. He said that team doctor Con Murphy hadn't been in touch concerning Tadhg Kennelly, who had been nursing a back injury.

"We played a practice match at Croke Park last week and Tadhg told me that he had a bit of an ankle injury, and with his club match coming up would like to play only half an hour. But Con hasn't been on to me and I'm assuming that he's fit."

As part of the Social and Recreational Games subcommittee's strategy to highlight the need for GAA clubs to develop a social aspect to their playing activities, members of Dublin's Naomh Mearnóg club will give a demonstration of social football at half-time in Sunday's International Rules test.

Among those who will be taking and organising the demonstration part is former Dublin All-Ireland medal winner Mick Kissane.

Players of all ages and abilities can play the game where only accidental contact is permitted. On Sunday, men and women of varying skill levels and abilities and ranging in age from 16 to 60 will play at Croke Park.
