Both sides need a win and Wolves are expected to bring around 5,000 supporters with them.
"Get yourself up there because we need you on Saturday," said Coleman to the CT. "It is the biggest game of the season for us when we can seal our status in the Championship. So if you have not been coming of late, for whatever reason, please, please get down on Saturday and shout for the lads."
"Wolves are only up the road so they will bring a lot of fans down and it looks like it will be a big crowd, and our fans can play a massive part and they are important, especially at home."
Tickets for the game at Charlton are selling well and anyone planning on going is advised to contact the ticket office asap.
