Jordan Archer didn't have the best of days:
Disaster struck for the Cobblers on 67 minutes. A harmless Myles Weston cross was floated into Archer but the goalkeeper spilt it and, although Corr did not initially realise, he did collect the loose ball and took it around Archer, who put out a hand and brought the striker down.
Archer was sent off for the incident and Corr buried the penalty, high into the roof of the net.
