Rasheedat Ajibade made her debut for Avaldsnes in their 1-0 defeat to Klepp in a Toppserien's encounter at the Klepp Stadium.
The Nigeria international was unable to rescue the visitors from bowing to last season's runners-up.
Ajibade came on in the 63rd minute of the second half to replace Erika Alves De Moura but she could not cancel out Elisabeth Terland's first-half strike.
The Super Falcons forward ended her nine-year-long journey with FC Robo to sign her first professional contract abroad after impressing at the 2018 African Women's Cup of Nations in Ghana.
With Saturday's loss, Avaldsnes are 10th on the Norwegian topflight log after their opening game and they will welcome Lillestrom on March 30.
For Ajibade, she will be eager to help her side bounce back to winning ways in front of the home fans at Avaldsnes Idrettssenter on Saturday.
