Wolves have now won just once in 16 league matches and face a vital clash with fellow strugglers Bolton next weekend.
"It is an absolutely huge game next week against Bolton and it really is a must win," Edwards said.
"If we can win that, it really gets us back in the pack and we can really kick on from there.
"We just have to really concentrate hard on getting ourselves right this week and in a good frame of mind for Saturday.
"We will have the fans behind us at Molineux and hopefully we can get a victory."
