Uefa will inspect the Wembley pitch on Monday after criticism of the surface following last week's game between Tottenham and Manchester City.
That match - which City won 1-0 - was less than 24 hours after an NFL game on the same pitch, and gridiron markings and wear and tear were clearly visible.
Tottenham host PSV Eindhoven at the national stadium in the Champions League at 20:00 GMT on Tuesday.
A 'specialist pitch expert' and the referee will carry out the inspection.
