Scunthorpe boss Brian Laws feels his side have given the club a huge boost by ensuring their survival bid will go down to the wire.
The Iron, fourth from bottom, are three points adrift of the club immediately above them in the table, Colchester, who have a three-goal better goal difference with one game left to play.
"All round I have to say that the team put in a much better performance," said Laws after Karl Hawley's close-range effort clinched a 1-0 win at MK Dons on Saturday.
"It gives us the chance to end the season with dignity.
"That was vital, not just for the players, but also the staff at the club and most importantly the supporters.
"We now have the chance to take it right down to the wire, the very last kick of the last game."
Scunthorpe take on Swindon at Glanford Park with the visitors already assured of a play-off finish, while Colchester travel to Carlisle.
