Newcastle have insisted that Obafemi Martins is free to link up with Nigeria.
The striker has been selected for his country's friendly clash with Ghana at Griffin Park, Brentford on Wednesday.
Speculation had suggested that Newcastle would refuse to release Martins for international duty, following Glenn Roeder's admission last month that he would ask his only recognised fit striker if he could sit out the game.
However, Newcastle have informed the Nigerian FA they are happy for Martins to join up with his compatriots.
"Newcastle United wishes to make it clear that the club has not refused Obafemi Martins permission to join up with the Nigerian squad for their friendly game with Ghana this week," read a statement from the club.
"The club has written to the Nigerian FA to make that clear."
