Boss Ian Sampson will be left deflated by his side's haul of just two points from two winnable looking home fixtures this week and a play-off place now looks a long way away for Town.
Tozer gave the home side the lead in front of 5,000 at Sixfields but Vincenti equalised with twelve minutes left and Northampton were then reduced to ten men with Harrad dismissed.
Reaction to follow on Cobblers Mad.
