Millwall have not won a league game since April and were humbled 5-1 at home to Derby over the weekend, pilling the pressure on Lomas.
Several flashpoint moments involving unruly Millwall fans during the Derby game will mean the spotlight will be on the club when Blackpool, fresh from a 2-1 away win at Bournemouth, arrive at the New Den on Tuesday night.
He said after the Derby defeat: "If I was a fan paying for that, I wouldn't be happy.
"The players have to show more drive. When things aren't going right, you've got to stick together and still keep doing the right things.”
Fellow strugglers Bolton will hope they have more luck when they take on Nigel Clough’s Derby side as they bit to halt a run that has seen them lose four on the bounce.
Leicester City are also hot on the heels of the top two, thanks to an impressive 2-0 win over Wigan Athletic at the weekend. Leicester take on a Blackburn side who will still be feeling relieved after Jordan Rhodes’s leveller against local rivals Burnley at the weekend.
Reading will be keen to get their promotion push up and running again in Wednesday's other game after they were held to a bad-tempered 0-0 draw at home to Brighton on Sunday that saw both teams finish with 10 men.
