Recovering goalkeeper Jordan Archer "close to making a return"
Lions boss Neil Harris believes a taxing run of away games is just what his side needs as they look to cement themselves within the play-off positions.
"Coming away from The Den won't do us any harm," Harris told millwallfc.co.uk
Tuesday night's clash at Rochdale will mark the start of a string of matches away from The Den, playing Swindon Town before travelling to League leaders Sheffield United.
"We have played a lot of football at home over the last three months and going away will be good for us over the course of the next seven days. It will be a big test for us and it's one that we are looking forward to.
"Rochdale are a very attack minded team and it's a tough place to go, especially on a Tuesday night, but it's a brilliant one for us."
The Dale currently sit in 10th position and will be buoyed by their 4-1 lashing of Gillingham last time out.
"They had a great result at the weekend and we will give them the respect they deserve. For Rochdale to get into the play-offs they will probably think they need to beat Millwall on Tuesday night so it's a big game," Chopper added.
"It's also a big one for us because there were some frustrations after our goalless draw against Bury on the weekend. That frustration comes from completely dominating the match but not killing off the game. We had chances and some of the performances were really good - it's all about building on that tonight."
The Millwall manager is "hopeful" recovering goalkeeper Jordan Archer will prove fit for tonight's match after suffering a knock to his hip in the Emirates FA Cup victory over Leicester City.
"Jordan is getting closer all the time. We hope he will be back into the squad but if he's not ready for Rochdale then we will look to bring him back on Saturday."
