His arrival at the Presidential Hotel increased the number of players in camp to 20, giving head coach Eric Chelle a near-complete squad for the encounter.
Bassey joins fellow defenders Semi Ajayi, Emmanuel Ogbu and Emmanuel Fernandez, while goalkeepers Maduka Okoye, Arthur Okonkwo and Francis Uzoho are also available.
Okonkwo heads into the game in high spirits after keeping clean sheets in his first two appearances for Nigeria during their Unity Cup triumph in London.
In midfield, captain Wilfred Ndidi, Frank Onyeka, Raphael Onyedika and Fisayo Dele-Bashiru headline Chelle’s options, while Moses Simon, Akor Adams, Terem Moffi, Rafiu Durosinmi, Paul Onuachu and Philip Otele provide attacking depth.
The match kicks off at 8:45pm local time at Warsaw’s 58,000-capacity PGE Narodowy Stadium, with Nigeria set to face Portugal in another friendly next week.
