The home-based Nigeria players have started their preparations for next month's international outing in their Abuja camp
Super Eagles coach Gernot Rohr was present at the first training session of selected Nigeria Professional Football League players in Abuja on Wednesday.
Before announcing the final 22-man squad, 25 NPFL stars are being groomed for the international friendly match against Mexico at the Los Angeles Coliseum on July 4.
Rohr turned to the home-based team since his foreign-based players are unavailable due to their various clubs' pre-season programmes, which will start next month.
