More than 24,000 Charlton fans will be at a sold-out Valley on Friday night to cheer on the Addicks.
Just over 1,000 extra seats in the away end were made available yesterday for Charlton fans desperate to watch Lee Bowyer and his team take on Doncaster Rovers in the Sky Bet League One play-off semi-final, second leg.
The sellout means the Addicks will be backed by the largest home support at The Valley since 2012.
Supporters who are attending Friday evening's match are reminded to leave plenty of time to enter the ground due to the higher-than-usual attendance and are also urged to avoid bringing bags, if possible, to ease security checks upon entrance.
Those without a ticket can listen to live commentary of the game on Valley Pass. Valley Pass costs just £6.50 per month and will include full pre-game and post-game coverage from The Valley. Click here to purchase.
