Graz AK have applied to UEFA to change the game to Wednesday 16th February because the game clashes with Austria Vienna's UEFA Cup game with Atletico Bilbao.
Boro hope to receive an answer today, but would urge fans not to book travel arrangements until the date is once again confirmed.
Ed's Note: Where this news originated from I don't know because according to UEFA.com the Austria Vienna game is on the Wednesday and so doesn't clash with our game.
