Scunthorpe won 3-2 to move up to fourth in League One and improve their chances of featuring in the the play-offs.
However, the game could have easily finished a point apiece had Wallace not come up with a stunning block.
With the game in injury time, Wallace – who was lying on the ground – managed to leap up and nudge away a goalbound effort from James Meredith before landing back on the mud patch.
Heroic stuff indeed.
