With Bournemouth's Mark Travers also in the squad, Stephen Kenny has called up Bohemians keeper James Talbot.

Talbot has been in previous Republic squads, but is yet to earn a cap.

Bazunu, who spent last season on loan at League One Portsmouth, will miss Wednesday's home game against Ukraine, Saturday's Dublin contest against Scotland and the return match against Ukraine in Lodz, Poland on 14 June.

Carabao Cup-winner Kelleher started his third successive Ireland game in Yerevan. Bazunu sat out March's friendlies against Belgium and Lithuania through illness, but finished on the losing side as Eduard Spertsyan fired Armenia to victory with a 25-yard piledriver.

The Republic are yet to win a Nations League fixture in 11 attempts, but Kelleher is convinced manager Stephen Kenny's target of topping League B group remains achievable.

"Yeah, absolutely - it was a setback on Saturday with the result, but we still know we're good enough as a squad," he said.

"We've got some good results recently, so we're good enough to win every game remaining and top the group."

"It's great to get games in at international level. It's a very high level and it's really good for my development.

"I don't know what is going to happen at club level, obviously, but if you keep performing when you get the chance, hopefully I can stay in and keep hold of the jersey."
