Please see the below from Millwall Football Club ahead of Saturday's game at The Den.
"Millwall Football Club welcomes Charlton Athletic fans to The Den this Saturday, where you will be seated in the North Stand.
"The club reminds all visitors that it is an all-seater stadium, though it understands that in moments of excitement fans will want to stand up and celebrate or offer support to their team.
"Please be aware that Millwall are very keen on keeping the gangways clear as the rake on the away stand is steep and doing so will minimise the chance of someone falling down and injuring themselves or fellow fans.
"A large crowd is expected and so the club advises you to arrive early to avoid any delays entering the stadium. Millwall have a zero tolerance policy against pyrotechnics and there will be a strict search operation supported by detection dogs.
"Any person in possession of, or who uses a pyrotechnic, will be arrested. A new CCTV system has recently been installed at The Den which records 360 degrees all of the time and this allows the club to ensure a safe event.
"Concession areas will be open and selling alcohol inside the stadium.
"Finally, there may be a need to delay your departure at the end of the game but this will be communicated to you."
