The League Two trip to Oldham Athletic taking place on 3 November 2020 will kick-off at the new time of 6pm.
Originally scheduled to get underway at 7.45pm, the kick-off time has been brought forward for the midweek clash at Boundary Park.
Last season the visit to Oldham ended in a 1-1 draw as Ryan Broom netted an equaliser to secure a point.
The Latics are under the management this season of former Liverpool and Australia international Harry Kewell, who replaced Dino Maamria as boss during pre-season.
