Brighton boss Graham Potter says Aaron Connolly has learned from his COVID-19 regulations breach and has declared the forward fit for international duty.
Albion sanctioned the young forward after he broke lockdown rules in the UK when he recently invited a woman to his home.
"He knows he's made a mistake and let himself and the team down and he's accepted that, we have dealt with that and we have moved on," Potter said of the incident and the club's investigation.
"He understands what has happened but we have to move on and accept the mistake and move on."
Connolly sat out Brighton's crucial win against relegation rivals Newcastle at the weekend as he recovers from a broken rib but the Brighton manager says he's ready to play for Ireland in their World Cup qualifier against Serbia on Wednesday.
"He has been injured. I felt he needed a few more days' training before he was available for the bench and I think he will get that when he goes away with the national team.
"That is good for us and it is good for him. He has just had a couple of days training so we did not want to rush him back. He needed more time. He will be available for the Irish national team and I think that will be good for him.
"Aaron has been really good. He's trained, he's been injured, he cracked his rib. He has trained the last few days and trained really well."
