Vadaine Oliver and Olly Lee put the Gills in control, but Ryan Edmondson and Fraser Horsfall rescued a precious point for Town. Here are our player ratings...
13. Mark Marshall
A real livewire on the right when introduced. Cobblers got him on the ball as much as they could and he caused plenty of problems for Gills. Only denied a screamer by a spectacular goal-line clearance... 7
14. Ryan Edmondson
He too made a big impact off the bench. Bonham initially thwarted his glancing header with a tremendous save, but he was not to be denied when sweeping into the bottom corner to kick-start the comeback... 7.5
15. Caleb Chukwuemeka
Arguably the most impressive of all four subs. Involved in both goals, knocking the ball down for Edmondson to finish and then helping win the corner for Horsfall's leveller. Some classy touches and a real menace when he got the ball at his feet.. 7.5
