The left-back, currently on loan with the Hatters from Premier League side Sheffield United for the season, has been picked by Ryan Giggs for the friendly against England next week, then the UEFA Nations League ties against the Republic of Ireland and Bulgaria.
The England match takes place on Thursday 8th October with an 8pm kick-off at Wembley, before Wales head to Dublin for a 2pm kick-off at the Aviva Stadium on Sunday 11th October and a 9.45pm kick-off in Sofia the following Wednesday.
Twenty-one year-old Norrington-Davies, who has impressed in his six appearances for the Hatters so far, will hope to add a first senior cap to the 14 he already has to his name at Under-21 level.
Goalkeeper Simon Sluga also heads off to join up with the Croatia squad following Saturday's game against Wycombe at Kenilworth Road.
Croatia travel to Switzerland for a friendly on Wednesday 7th October, before hosting Nations League matches against Sweden and France in Zagreb on the 11th and 14th.
Congratulations and good luck to both Hatters on international duty!
