Morley took a massive step towards survival in National Three North on Saturday when they clinched a crucial four-point win at fellow strugglers Firwood Waterloo.
The 16-10 triumph lifts the Maroons out of the bottom three and above Cleckheaton and Doncaster Phoenix, who both lost at the weekend.
Morley also boast a game in hand on their rivals, and that will be played on Saturday when they travel to third-placed Hull.
With only five fixtures of the season remaining, Morley must make every game count but the relegation battle looks destined to go to the final day of the campaign.
Morley made a blistering start to their trip to Waterloo and were 10-0 up after only seven minutes, thanks to tries from Ben Bowen and Iain Sim.
Waterloo responded with their own period of pressure and were rewarded with try from a rolling maul on 18 minutes when hooker Scott Robson was driven over.
Home flanker David Gairn was yellow carded for a deliberate knock on and Chester calmly kicked the penalty, which was to prove vital in the final reckoning.
Will Smyth and Judd Newell both thought they had added to the try tally but saw their efforts ruled out by the referee.
Waterloo made the better start to the second half and pinned the visitors back in an intense spell, which ended with the home side crossing for a try on 53 minutes, which reduced the arrears to six points.
In a nail-biting finish, Waterloo battered the Morley line only to be met by a determined defence.
The pressure resulted in two sin-binnings for the visitors but they held on to claim a massive win.
