The state of the pitch after the U2 concert took place came under fire from a number of opposing teams.
One end was left badly discoloured and combined with the bad weather over a number of weeks this winter, the pitch required parts of it to be re-laid.
The Wembley pitch has had its own problems, with the ball visibly taking a bobble when running on the surface.
The Millers will only be allowed to view the pitch on Friday before the League One Final takes place on the Saturday.
