Wojciech Szczesny has pulled out of the Poland squad because of a back injury.
As a result, the Arsenal goalkeeper will now play no part in his nation's two upcoming friendlies against South Korea and Belarus.
The 21-year-old was due to join up with his international teammates later this week but coach Franciszek Smuda has called up Genk goalkeeper Grzegorz Sandomierski as his replacement.
Many reports suggested that Szczesny was at fault for Tottenham's winning goal during yesterday's North London derby at White Hart Lane.
He has represented his country on six occasions.
