Northern Ireland winger Caragh Hamilton will miss October’s Euro 2025 play-off with Croatia because of a “significant” hamstring injury.
Nottingham Forest manager Carly Davies said that Hamilton, 27, will be on the sidelines “for a prolonged period of time”.
Davies said: “She’ll be working closely with the medical team with the support of the Northern Ireland national team as well.
“We’ll just be hoping to get her back on the pitch as soon as possible.”
Hamilton joined Forest, who are unbeaten in eight matches in the FA Women’s National League Premier Division North – in the third tier of English women’s football – from Lewes in the summer.
She has won 46 Northern Ireland caps and scored six goals.
Tanya Oxtoby’s side travel to Croatia on Friday, 25 October before the return fixture at Windsor Park on Tuesday, 29 October.
Northern Ireland qualified for the play-off by finishing second in Group B3, with three wins from six matches.
Croatia were third in Group B4, behind Wales and Ukrainez, and if Northern Ireland progress they will face Norway or Albania for a place at the Euro 2025 finals.
