David Jones hopes the win over Derby will give Blackburn the confidence to win Tuesday's equally crucial Championship clash with Huddersfield.
Rovers beat Derby 2-0 at the weekend to claim a first league win since February 9th and move out of the bottom three.
Victory over fellow strugglers Town at Ewood could go a long way towards preventing the humiliation of a second successive relegation.
Midfielder Jones, who is on loan for the rest of the season from Wigan, told Rovers Radio: "It was exactly what we needed, and we know that it is the minimum for us to get out of the situation that we are in.
"Hopefully it will give us confidence going into Tuesday. It brings the group together. In the dressing room afterwards the whole squad was delighted.
"We want to replicate that feeling again, starting this Tuesday in another massive game."
