ADEYBAYO AKINFENWA scored against his former club and Fred Onyedinma missed a second-half penalty as Wycombe knocked Millwall out of the Checkatrade Trophy.
Akinfenwa scored a 51st-minute penalty to put Wycombe ahead before David Worrall levelled for the home side. Just when it looked like a poor game would be decided by penalties Garry Thompson scored a late double to send Wycombe through to the last 16.
The best chances of the first half fell to Onyedinma but his heavy touch around Jamal Blackman took the ball wide, before Blackman saved at the attacker's feet moments later.
Three minutes before the break Joe Martin crossed from the left to find Onyedinma whose header deflected out for a corner, before Ben Thompson's shot hit Martin and Wycombe cleared. That moment summed up a game desperately short of quality.
Wycombe boss Gareth Ainsworth introduced Akinfenwa for Paul Hayes at half-time and his side were immediately more vibrant in the second half. When Stephen McGinn shot in the box in the 51st minute referee Dean Whitestone deemed Sid Nelson had clipped him, and former Lions striker Akinfenwa beat Tom king from the spot.
Millwall were level two minutes later. Shaun Cummings combined with Worrall on the right, and the winger seemed to be aiming a cross into the box but the ball instead found a way through Blackman at his near post.
In the 67th minute Onyedinma latched onto Kris Twardek's pass and was through on goal before defender Aaron Pierre seemed to bundle him over outside the box, but Wycombe escaped punishment.
Two minutes later the same two players came together again near the endline and this time Whitestone immediately pointed to the spot when Onyedinma tumbled. Onyedinma had already scored a penalty this season, at Barnet in the League Cup in August, but here Chairboys goalkeeper Blackman read the direction of the strike to save to his left.
Wycombe were claiming another penalty when the ball appeared to strike Butcher's arm. But they went back in front when five minutes from time when Thompson fired home from 15 yards.
Twardek fired a first-time volley over from Worrall's corner with a minute to go, before Thompson added his second in added time when he tapped home substitute Scott Kashket's cross after a swift Wycombe counterattack.
