A late Paul Mullin header broke Wycombe's hearts in the final few minutes at Adams Park.Blues knew a win would keep matters in their own hands in the bid to win promotion but they came up against a determined Morecambe side who created the better chances, leaving Wycombe grateful for the intervention of Matt Ingram on a number of occasions.
Gareth Ainsworth was forced into a reshuffle due to Aaron Pierre’s absence through injury, and there was a further blow when Sam Saunders pulled up in the warm-up, meaning Marcus Bean and Max Kretzschmar came into the side.
The two teams were greeted by an electric atmosphere and Blues began brightly, with Peter Murphy coming closest to scoring when his half-volley flashed past the post from Paul Hayes’ lay-off.
Mark Hughes’ header was easily gathered by Matt Ingram in the visitors’ first opportunity, before the chances dried up at both ends even though Wanderers continued to look enterprising with their three-pronged attack.
Ingram had to be alert again in first-half stoppage time to deny Jack Redshaw with his feet, before Wood drilled wide from distance just after the interval, and Ingram held on comfortably to Kevin Ellison’s low drive from just inside the box.
Wycombe came close to breaking the deadlock when Alfie Mawson connected with a corner from the right but his header bounced back off the crossbar and fell to safety.
Hughes had another chance at the other end, finding space to connect with a deep corner only for Ingram to deny him, before a foul on Fred Onyedinma on the edge of the box gave the Blues a free-kick in dangerous territory, but Nico Yennaris’ effort came back off the wall.
The patched-up Wycombe backline was having trouble dealing with Morecambe’s deliveries into the box and Hughes found himself again denied by Ingram with a stunning save after the defender glanced on Jamie Devitt’s teasing cross.
Ingram was keeping his side in it and tipped over Padraig Amond’s looping header before keeping out Ellison’s goalbound header with another one-handed save.
But the heartbreak inevitably arrived when Morecambe found the net with just a few minutes remaining, at exactly the same moment that Southend broke the deadlock in their game at home to Luton. A deep cross found Paul Mullin in space and his header found a way past Ingram, leaving Wanderers with an uphill struggle to keep their promotion hopes in their hands.
Four minutes of added time came and went to leave the Blues contemplating a likely play-off finish after their best ever points tally in a Football League season, although there could still be a twist to come on the final day.
