Republic of Ireland manager Mick McCarthy will give Shane Duffy and David McGoldrick every chance to prove their fitness ahead of the Euro 2020 qualifier double header with Georgia at Switzerland.
McCarthy's squad travel to Georgia on Thursday and the manager is hoping that the duo can overcome injuries to be part of the travelling party.
McGoldrick is nursing a groin injury while Duffy is recovering from a injury sustained in Brighton's League Cup defeat to Aston Villa last week.
"Our medical team are in constant touch with the two clubs and monitoring the treatment programmes and progress for both Shane (Duffy) and David (McGoldrick)," McCarthy told FAI.ie.
"We will give both of them as much time as we can before making that decision. Both Brighton and Sheffield United are doing everything they can to get them fit for us and I would like to thank them for their co-operation."
McCarthy added Brighton & Hove Albion striker Aaron Connolly and Blackburn Rovers defender Derrick Williams to his squad on Saturday evening after the withdrawal of the injured Ronan Curtis, Darragh Lenihan and Greg Cunningham.
Connolly, who made a stunning first Premier League start on Saturday, and Williams both joined up with the squad at their hotel on Sunday evening and will train at Abbotstown on Monday afternoon.
"Aaron Connolly and Derrick Williams are in camp now and I will see how Shane and David are doing before finalizing the travelling party for Thursday's flight," the Ireland manager added.
"I've said all along that any young player who is getting first team football and playing well would be a real contender for the squad for these games. Aaron has got into the Brighton team, played well and scored so he deserves this chance.
"Jeff (Hendrick), Conor (Hourihane) and Scott (Hogan) were on the scoresheet as well on Saturday so they will be buzzing looking ahead to Georgia and Switzerland."
Ireland take on Georgia in Tbilisi on Saturday before travelling to the Stade de Geneve to clash with Switzerland three days later.
