9. Sam Hoskins
Clearance was so poor and then compounded the error by nudging Charsley. Contact was minimal but it was naive defending and gave the ref a decision to make. Needless so early into the game and ultimately proved very costly... 2 Photo: Pete Norton
10. Callum Morton
Still waiting for his first home goal. Didn't get many shooting chances against Mansfield and when he did, he couldn't get the ball out from under his feet. Worryingly forced off with a hamstring problem... 6 Photo: Pete Norton
11. Vadaine Oliver
Spectacular overhead kick so nearly hauled Cobblers level on the stroke of half-time. Not terribly effective though and benefitted from Smith's arrival... 5.5
12. Harry Smith
Made a positive difference as a half-time sub, so close to levelling when his header landed just in front of Morton and narrowly wide of the far post. Great finish in stoppage-time, if only a consolation... 6.5
