Sheffield Tigers are just five league points away from qualifying for the National Three Midlands Play-Offs.
The Dore Moor club stormed from behind to score a 36-20 win at Old Northamptonians, and need to score at least four tries at Scunthorpe on Saturday to earn a place in the play-offs against Chester, the second placed club in National Three North.
A five point win will put them level on league points with Stoke club Longton, currently the second placed side in national Three Midlands, but Tigers would go through to the play-offs by virtue of having won 21 matches to Longton’s 20.
Tigers looked to have blown their chances when they trailed 20-7 early in the second half of their match at Northamptonians.
They had gone ahead when prop Sam Lockwood crashed over for a try after just four minutes, Johnny West converting, but the home side hit back with two converted tries and a drop goal to lead 17-7 at the turnaround.
Tigers launched their fightback when stand-off West found a gap in the defence and ran through to score, and he converted his own try as well as another from second row Richard Joel.
Replacement back row Frank Wragg was next to score, West adding the points. Jon Feeley then ran through from halfway to score under the posts, and Tigers sealed their win with West’s late penalty.
Sheffield RUFC are already assured of a play-off after sealing second place in Yorkshire Division One with a 28-17 win at Castleford.
The Abbeydale Park outfit, who will play Darlington on Saturday for the chance of promotion to North One East, collected a four try bonus point, with two of the touchdowns coming from winger Alistair Womack.
Flanker Laurence Thomas and centre Ewan Reed also scored, and Nick Cook converted one as well as landing the opening two penalty goals.
Dinnington capped their good finish to the season with a 27-15 home win over third placed club Heath.
Prop John Marshall, second row John Stimpson, flanker Ryan Donnelly and winger Dave Longstaff crossed over for tries.
Rotherham Phoenix also came from behind for a 20-7 Yorkshire Three win over Old Modernians at Leeds.
