Spencer had already been involved with England's youth sides before he scored against them on Friday.
Spencer arrived at Leeds from Sunderland earlier this year, despite reports that Manchester City were among the clubs interested in signing him.
The 15-year-old had already been involved with England's youth sides, despite his Norwegian mother having contacted her country's football association regarding her son's eligibility (Teesside Gazette).
But Norway have finally taken note and included Spencer in a 19-man squad to face England at St George's Park earlier this month.
The game was played earlier on Friday and ended in a 2-1 win for the Three Lions, despite Spencer's goal, which he dedicated afterwards to his mother.

Spencer, who doesn't turn 16 until March 2020, has already played for Leeds U18 side this season.
He will remain eligible for both England and Norway until he appears in a competitive senior fixture.
