Troost-Ekong is one of the 26 players invited by Nigeria caretaker coach Salisu Yusuf for the friendly matches against Mali and Luxembourg next month.
“Very happy to be called up again for Nigeria. Hard work pays off,” he tweeted.
The 22-year-old defender, who is on loan at the Norwegian club from Belgian champions Gent, has four caps for Nigeria.
He represented Holland at youth level before he decided to change his international allegiance.
Meanwhile, former Nigeria youth international Chidiebere Nwakali scored his first-ever goal for Norwegian club IK Start on Wednesday in a 3-0 win over Fram Larvik in a cup game.
Nwakali, who is on loan from Manchester City, hit the target in the 72nd minute to give his side a 1-0 lead.
The older brother of Flying Eagles skipper Kelechi Nwakali lasted for 82 minutes when he left the pitch for another Nigerian Austin Uzoremeke.
