It is thought that the players suffering with the virus are David Dunn and Chris Samba although that has not been confirmed by the club. Both missed the debacle against Chelsea.
The game could have been called off if Rovers had applied for special dispensation from the FL, but the club are willing to play the game.
Club secretary Andrew Pincher said: "There has been speculation in the national media following confirmation of sickness within the camp, but we can reassure all supporters that the tie will go ahead as planned."
