Lions must "stand strong" against Rovers' front men at The Den
Both Millwall and and Bristol have scored more than 24 goals this season and Neil Harris has spoken of the importance of standing strong against Darrell Clarke's lethal attacking unit.
"Darrell has done a really good job to turn Bristol around," Harris told millwallfc.co.uk
"They play with energy, freedom and can definitely score goals. It has the makings of a very good match, with both teams really going for it."
Former Lion Jermaine Easter is expected to make his return to The Den alongside strike partner Matty Taylor, who has already netted 11 times this season.
And while the Millwall manager says Easter will have 'nothing to prove' tomorrow, he does predict the Bristol striker won't be lacking in motivation when he runs out against his old club.
"Jermaine is a top pro and it's our job to make sure he doesn't come back to haunt us," said Chopper. "An ex-player going back to his old club, he is always going to want to do well against us."
Both managers may be forced to shuffle their playing packs for the match. Striker Steve Morison is being monitored after falling awkwardly on his knee against Southend United last week, along with Ben Thompson, who was also forced off in the first-half. "We hope he is going to be fit for Saturday, if not then we will slightly adjust to the way we play.
Meanwhile, Bristol Rovers defender Mark McChrystal will watch from the sidelines after being suspended for the trip, while Charlie Colkett, Lee Mansell and Billy Bodin are all expected to be fit after being struck by illness last week.
Harry Smith had a brilliant night in our mid-week match with Luton Town, scoring two goals. He gives us something similar to Steve, albeit a lack of experience. We do have options available to us."
