Reading fans travelling by rail to Saturday's trip at Millwall will face disruption.
South Bermondsey station, the nearest point to the Den with it's own 'away fan only'' footpath directly to the turnstiles, is to be closed due to engineering works.
However, there are rail replacement buses running every 15 minutes to try and limit the impact.
So far more than 1,000 Royals have purchased tickets for the match, with plenty still available before the Friday lunchtime cut-off.
Royal Mail are on strike this week, with the deadline for sending tickets to supporters' address having closed today.
The club encourage fans to pick up their tickets from the SCL ticket office in advance of the fixture.
A difficult period for disruption, many Blackburn Rovers fans returning from their 3-0 defeat to Reading last week encountered difficulties after the M4 was closed overnight.
