Republic of Ireland forward Aaron Connolly will undergo a scan on Monday afternoon after limping off at half-time with a groin problem in Brighton's 3-1 Premier League defeat to Manchester United on Sunday afternoon.
Ireland boss Mick McCarthy confirmed that Connolly will undergo a scan at 2.45pm which will determine his availability in the upcoming friendly against New Zealand at the Aviva Stadium on Thursday and the crucial Euro 2020 qualifier at home to Denmark four days later.
"He is going for a scan this afternoon. I won't know anything about that [his availability] until we get the results," said McCarthy.
"I don't know how bad it is."
Connolly made an instant impact on his senior international debut last month when he came off the bench in Georgia and very nearly snatched a win which would have edged Ireland closer to a place at next summer's finals.
The 19-year-old was handed a first start in Switzerland three days later on the back of his performance in Tbilisi, but found the going tougher as his side went down 2-0 in Geneva.
That result left them needing to beat the Danes at the Aviva Stadium next Monday evening to qualify automatically, barring a shock result elsewhere.
Connolly's Brighton and Ireland team-mate Shane Duffy came through the encounter against the Red Devils unscathed.
