Nothing could separate the Blues and promotion-chasing Northampton as the two sides played out a goalless draw at Adams Park.
Defences were on top throughout with Adebayo Akinfenwa’s second-half header, which rebounded back off the post, the closest either side came.
Gareth Ainsworth made three changes to the side that beat Aldershot with Marvin McCoy, Leon Johnson and the available-again Stuart Lewis coming into the team.
Michael Harriman and Sam Wood were named amongst the substitutes, while Dave Winfield missed out with the calf injury that forced him off against the Shots.
Wanderers started well and Matt McClure’s effort was deflected inches wide after Grant’s clever cut-back to the near post.
However, it was the visitors who came closest to an early goal when Chris Hackett’s cross was partially cleared by Matt Ingram and Roy O’Donovan headed wide. Luke Guttridge then half-volleyed wide from just outside the area.
Saturday’s match-winner Joel Grant tested Lee Nicholls in the 18th minute, but his 25-yard strike was straight at the keeper who parried away.
Both sides were struggling to create chances and Dean Morgan headed Spring’s lofted free-kick at Nicholls just past the half-hour mark.
Ingram was called into action two minutes after the restart and he made a smart stop low to his right to keep out O’Donovan’s header from Hackett’s right-wing cross.
Hackett was involved again a minute later and this time the visitors were denied by the woodwork as the winger’s cross was headed past Ingram by Adebayo Akinfenwa, but rebounded back off the crossbar.
Ben Tozer then had an effort deflected wide and Clarke Carlisle headed the resulting corner over as the Cobblers started the second half in the ascendancy.
McCoy had the Chairboys’ first strike after the interval, but his powerful 25-yard shot flew wide of Nicholls’ goal.
Carlisle headed at Ingram from Ben Harding’s free-kick, but the Wanderers broke quickly and McClure lofted over the bar after breaking through on the left-hand side of the area.
Ainsworth’s men weathered the storm and Morgan inadvertently deflected Spring’s 20-yarder in the 68th minute, but it fell for Nicholls.
Ingram denied Akinfenwa again in the 72nd minute, but Blues looked threatening on the break and Spring came close from 25 yards.
Both teams pushed for a winner, but Dunne crashed over from long-range and Ingram made a brave save from Akinfenwa with a Northampton attacker in close proximity.
