The ticket office at Whaddon Road is open until 4pm on Tuesday and 3pm on Wednesday for any fans wanting to avoid queues at the turnstiles as Steve Cotterill makes his first competitive return to his hometown club.

The park and ride will be operating as normal, but there are no pre-booked parking spaces available at the ground.
All hospitality suites at Whaddon Road are sold out.
