The Cobblers have until 12pm on Monday to decide whether to appeal against John-Joe O’Toole’s sending-off at Mansfield.
The midfielder was dismissed in the 32nd minute of the game and will now serve a three-match suspension for violent conduct.
But video footage of the incident seen by the Chron is inconclusive and could lead the club to make a bid to have the decision, and therefore the ban, overturned.
On the film, it appears Mansfield defender Ritchie Sutton has O’Toole in a headlock and the Northampton midfielder then leans into him as he falls to the ground.
It does not appear any punch is thrown or any stamp aimed at Sutton by O’Toole when he is on the ground.
Meanwhile, the club will take no further action after it was revealed a club official was spat at by a Mansfield supporter in the immediate aftermath of the sending-off.
The incident took place in the Field Mill press area, which is situated in the ground’s main stand.
