Republic of Ireland boss Mick McCarthy has no plans to add to his squad ahead of Tuesday night's friendly against Bulgaria despite losing two players to injury.
Sheffield United pair David McGoldrick and Callum Robinson have returned to their club to undergo treatment for shoulder and hamstring injuries respectively, but they will not be replaced.
Twenty one of the remaining 22 members of the squad were due to resume training at Abbotstown on Sunday afternoon after being given time off in the wake of Thursday night's 1-1 Euro 2020 draw with Switzerland.
Derby defender Richard Keogh was the only absentee, but he was expected to report back on Sunday evening.
It means Luton Town attacker James Collins could make his Ireland debut in Dublin.
The 28-year-old and with Scott Hogan are now the only two recognised strikers in the panel . Coillins has scored three times in the Championship this campaign. The newly promoted Hatters are 15th in the table.
"My family are flying out and hopefully they'll see me get my first cap," said Collins on Sunday.
"Me and John Egan were talking the other day - it was not so long ago when we were playing against each other in League One for Gillingham and Shrewsbury.
"So to see how far we've both come since then - obviously, John playing in the Premier League now and myself in the Championship - it can show any young player that, if you do have a setback, you can only bounce back if you work hard."
