The 24-year-old striker, who has three goal contributions in his first five Championship appearances of the new campaign, will link up with Brian Riemer’s squad after injuries to Brentford’s Mikkel Damsgaard and Stuttgart’s Nikolas Nartey.
Kvistgaarden’s only previous senior international cap came under Riemer, who has been in charge since October 2024.
The attacker has also scored at the Cardiff City Stadium in a League Cup win earlier this season for the Canaries.
“Mathias has found his form again,” said Riemer, speaking at his pre-match press call on Saturday.
“He has been getting a lot of playing time for his club recently, and he is used to the British style. He knows what will hit him if he comes on the pitch.
“He is a multifunctional player in the attack. I can use him widely, he has played that many times in Brøndby. He can also play as a 10, and he can easily play as a nine.
“Unfortunately, it is clear that Mikkel Damsgaard, along with Nikolas Nartey, will not be available for the match against Wales.

“What we thought was a blow turned out to be a more serious injury. Just before leaving (for Wales) we found out that Mikkel could not play in Sunday’s match.
“It’s always difficult when you lose a player so late in a game. And even two. Normally I would consider not calling up a player, but when we lose two, we had to do it.
“Mikkel has shown really good form for the Danish national team for a long time. And also good goal scoring form. So he is a player who will be missed. There is no doubt about that.
“That said, Mikkel was only one player out of 11 on the field, and we still have many other fine players, so we have a more than effective team.”
Portugal top the current standings in League A – Group Four with three Nations League wins out of three, with the Danes, Norway and Wales on three points after three matches.
Kvistgaarden was one of three Norwich players on standby for their countries over the international period, along with Jovon Makama and Jacob Wright for England’s Under-21s.
Philippe Clement’s squad initially had 12 call ups but due to a range of fitness issues only senior trio Anis Ben Slimane, Ruairi McConville and Darlin Yongwa have seen action over the past fortnight.
