Promotion-hopeful Wycombe managed only to secure a 0-0 draw against bottom-of-the-league Shrewsbury despite taking 30 shots at Adams Park.
The home team missed the opportunity to reduce the gap on second-placed Wrexham, who were held at Cambridge and are still three points ahead with one more game played in the League One promotion battle.
The Chairboys entered the game aiming for their third consecutive league victory, a feat they had not accomplished since November, and controlled the first half of the match.
Leading goal scorer Richard Kone came close on two occasions but missed the target with his shot before heading wide from a Jasper Pattenden delivery.
Former Wycombe goalkeeper Jamal Blackman was forced to make a fantastic save to stop Xavier Simons' long-range bending attempt, while Garath McCleary and Cameron Humphreys missed the target.
On the other hand, Shrewsbury had two clear opportunities to score, both falling to George Lloyd, who failed to capitalize on either.
In the second half, Wycombe pushed forward aggressively, with McCleary, Cameron Humphreys, and Kone all coming close to scoring.
Simons once again found his efforts denied by Blackman, as Sonny Bradley, Sam Vokes, James Berry, and Jack Grimmer created chaos in the Shrewsbury penalty area, but Michael Appleton's team defended resolutely.
