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."
The 25-year-old missed nearly three months from September with the injury and he sat out almost all January and although he has returned to the starting line-up on a regular basis he is still hampered.
Gibson scored from long-range in Saturday's 2-0 win over QPR, only his second goal since signing from Manchester United in January 2012, and Moyes would like to see him do it more frequently but believes it is not possible currently.
"After the game on Saturday, I was asked about Darron Gibson's goal and his shot - I think he could do it more and with more ferocity as well because he's got a great shot on him," said the Scot.
"He has got a bit of a problem at the top of his thigh which will probably require an operation at the end of the season."
Despite not being 100% Gibson has added a different dimension to Everton's midfield with his vision and distribution.
"What he has given us is that he is good on the ball and he has a better range of passing than maybe some of the other midfielders we have," added Moyes.
"I think overall he has had an impact. He had a bit of a dip midway through after he came back from his injury but his form is good right now."
