The 24-year old, who is the current Republic of Ireland WNT Player of the Year, had travelled with the squad to Stavanger in hope of featuring but has now been ruled out through injury.
Louise Quinn is set to play the qualifier against Norway, despite suffering a fractured nose in Friday's 2-0 defeat at Tallaght Stadium. Quinn has had a protective mask fitted and should feature for Colin Bell's side tomorrow night.
The squad trained at the Viking Stadion earlier today ahead of tomorrow's match which is live on RTE2, with kick-off at 5pm (6pm local time).
Republic of Ireland WNT Head Coach Colin Bell said: "We worked hard with Harriet to try and get her fit but it wasn't to be.
"I'm never going to risk the health of one of my players so I've made that decision to leave her out. It's been great to have her around the squad though as she's an important part of the journey we're on and a great influence on the other players.
"We've been able to get Louise a mask so she should be ok for the match. We'll obviously monitor it to make sure she feels she can play with the mask but her desire to play has been admirable.
"As soon as it happened, she wanted to get back on the pitch but we had to hold her back. It shows the passion and determination the players have for this team. They want to succeed and that's fantastic for me to see."
Aine O'Gorman is set to win her 100th cap if she features tomorrow night. The Peamount United star made her debut in 2006 against Denmark and will reach the milestone against Norway after a 12-year international spell.
Ireland need a result to keep their qualification hopes alive with just two games in their FIFA 2019 World Cup qualifying campaign left and Bell believes the players are prepared.
"It's a simple equation for us now and in many ways, that can make the picture a lot clearer for the players," Bell said.
"We've obviously just suffered defeat against Norway but we've been able to pick out so much from that game which we can learn from. There were a lot of uncharacteristic mistakes in the game and the players have been able to see that.
"We've got to take what we've learnt into tomorrow night's game and try our best to get the result we need. We've made a lot of progress throughout the campaign but we want to go all the way and so do the players."
The WNT Head Coach has limited options in defence with SC Sand defender Diane Caldwell suspended for the fixture after picking up her third yellow card of the campaign in Friday's defeat.
