Munster centre Rob Henderson and Ulster wing Tyrone Howe have received late call-ups to the Ireland squad for Saturday's World Cup warm-up match against Scotland in Murrayfield.
The pair headed for Dublin after Denis Hickie and Kevin Maggs both suffered groin strains at training.
Both Maggs and Hickie will have fitness tests this morning prior to the Ireland team departing for Edinburgh today.
Scotland's new captain Gordon Bulloch has called for Scotland to put their 23-9 defeat to Wales behind them.
"Manchester United go into every game full of confidence," he said. "The game against Wales was a setback, but we have talked about it. We have watched the video and we have cleared our minds and we know what has to be rectified."
Pedro Sporleder, meanwhile, squeezed into Argentina's 30-man World Cup squad yesterday when it was cut from the provisional 38 named by the coach Marcelo Loffreda in July.
The lock will join front-row forward Federico Mendez and the centre Lisandro Arbizu as veterans of four World Cup campaigns.
Argentina, who are in Ireland's group, have found a place for Patricio Albacete, another lock, and the back rowers Martin Durand and Pablo Bouza. Arbizu will captain the Pumas again, having led them to their best World Cup finish in 1999 when they upset Ireland to reach the quarter-finals.
The Pumas will meet Ireland again in Group A of this year's tournament after facing Australia in the opening match in Sydney on October 10th.
Namibia, who are also in Pool A along with champions Australia, Argentina, Ireland and Romania, also named their squad yesterday and confirmed their coach Dave Waterson would definitely lead them to Australia.
Dirk Conradie, the president of the Namibia Rugby Union, said the New Zealander would remain in charge despite a revolt in the training camp last week which saw two players and an assistant coach withdraw from the squad.
"There is no way we can take another coach to Australia," Conradie said. "The players did not appoint the coach. The rugby union appointed the coach."
The dissident trio had criticised tactics and the long absences of the coach, who is based in South Africa.
Namibia's squad includes 11 players who played at the last World Cup, when they reached the final stages for the first time.
The number eight Sean Furter takes over as captain from Corne Powell. Conradie said Furter was more experienced and commanded more respect.
