Sean Dyche's men are unbeaten in seven league matches, but remain 11 points adrift of top spot.
However, they play their game in hand over Leicester when they make the trip to the Reebok Stadium to take on a Bolton side scrapping for their lives at the wrong end of the table.
Bolton's draw against Bournemouth on Saturday was their first point in almost a month, and they have been dragged dangerously close to the relegation zone following their poor run.
"We feel like we've dropped two points," he said following the Bournemouth clash. "But we have got to stick together and ensure that we keep battling away.
"We've shown that we have got goals in us. We just need to make sure that instead of performing for patches of the game, that we’re right at it for the full 95 minutes."
Gary Johnson's side can bounce back from that disappointment when they welcome Millwall, while three other Championship games see Sheffield Wednesday host Wigan Athletic, Nottingham Forest travel to 13th-placed Huddersfield Town and Watford face Birmingham City.
The pick of the games in League One sees high-flying Leyton Orient host relegation-threatened Bristol City, with the home side having suffered back-to-back league defeats for the first time this season courtesy of Saturday's dramatic 2-1 loss to Peterborough United.
"It hurts but we can't sulk," Orient boss Russell Slade said. "It's part of our journey. We need to put it right on Tuesday night."
In Tuesday's other League One games, Port Vale host Colchester United and Bradford City travel to Carlisle United, while on Wednesday FA Cup heroes Sheffield United welcome current league leaders Brentford.
