Troy Parrott has been named in Mick McCarthy's final Republic of Ireland squad for the decisive Euro 2020 qualifier with Denmark on Monday week.
The Tottenham striker wasn't included in Stephen Kenny's Under-21 squad earlier this week. Instead, he'll get a chance to shine in the seniors' friendly against New Zealand which takes place four days before the Danish game.
Southampton striker Shane Long meanwhile has been chopped from he squad.
"Troy Parrott is in the squad for the first time and he will feature against New Zealand next Thursday," McCarthy confirmed to FAI.ie.
"All he has to do is look at how well Aaron Connolly did last time in Georgia and Switzerland to see the opportunity that is there for him now.
"The same will apply for other players who will get a chance against New Zealand and can give me something to think about for the Denmark match. We know that's the game we have to win and I can’t wait to get into camp now on Sunday and start working with these players again."
David McGoldrick, who missed the games against Georgia and Switzerland, is included, as are Robbie Brady and Ciaran Clark.
Burnley midfielder Brady had missed out on the last qualifiers after McCarthy said he lacked game time, while the Ireland manager was in attendance as Clark scored for his club Newcastle at the weekend.
Like Parrott, Celtic defender Lee O'Connor (above) has received a call-up from the Under-21s panel and is set to see game time against the All Whites before rejoining Kenny's side for their qualifier clash with Sweden at Tallaght Stadium.
"With Lee suspended for the first of the two Under-21 matches, this is the perfect opportunity to have a look at him in the friendly, introduce him to senior international football and see how he gets on," said McCarthy.
"I've been impressed with him for the 21s and I know how important he is to them for that Sweden game so this is a win-win for all concerned.
"Robbie Brady was left out last month simply because he had only played three minutes in the Premier League all season when I named the squad.
"He is back involved with the Burnley first team now and getting game time and his involvement is a real boost to us ahead of the match against Denmark because of the quality he brings to the team.
"I will give Robbie time against New Zealand to get ready for Denmark. He is one of the players in the squad who will really benefit from the New Zealand game before we play the Danes.
"Ciaran is in the same boat. He had to get back with Newcastle before he could back with us but he is playing well for them now and I was impressed with him against West Ham last Saturday.
"David’s return is the big bonus for all of us. Everyone knows how well he has done for us in the European Championship games he has played this year and he has been brilliant for his club in recent weeks."
