A controversial Paris Cowan-Hall goal secured Wycombe a first win in seven games as they beat Grimsby 2-1.
The substitute struck after a Danny Collins own goal levelled things up following Calum Dyson's first-half penalty, but the hosts felt aggrieved when the goal came with one of their players down with a head injury.
Grimsby took the lead when Tom Bolarinwa was brought down by Sam Wood in the penalty area and Dyson sent goalkeeper Jamal Blackman the wrong way from the spot to put the hosts in front.
Wycombe found themselves level in freak circumstances in the second half as Blackman sent a free-kick deep into Grimsby's penalty area and Collins inadvertently flicked the ball over keeper James McKeown's head and into the back of the net.
The visitors took the lead with around 20 minutes of the game remaining, but it was not without controversy.
After McKeown punched the ball clear from a free-kick, Gavin Gunning went down with a head injury as Cowan-Hall superbly curled the ball into the top corner.
Gunning was stretchered off the field but the goal stood as Wycombe claimed a long-awaited victory.
