Rovers' trip to AFC Wimbledon early in the New Year will have to be rearranged.
Tony Mowbray's side were due to visit Kingsmeadow on Saturday January 6th 2018.
However, following the Dons' 3-1 victory over Charlton Athletic in the second round of the FA Cup, the League One fixture between the two teams will now require a new date, as the scheduled fixture falls on FA Cup third round weekend.
A date for the rearranged match will be announced in due course.
Rovers will require a replay to see if they will join AFC Wimbledon in the third round after being held to a dramatic 3-3 draw by Crewe Alexandra at Ewood Park on Sunday afternoon.
