Right-back Brendan Moloney is the Cobblers’ only injury concern ahead of Saturday’s trip to Yeovil Town.
The Irishman missed Tuesday’s 2-1 win over Crawley as a precaution after suffering pain in his knee, with Josh Lelan stepping in to play his first football since November.
Former Yeovil defender Moloney was set to take some part in training today (Friday), is travelling with the squad to Huish Park.
Wilder hasn’t written off the 27-year-old’s chances of playing, but if he doesn’t the Cobblers boss has 100 per cent confidence in youngster Lelan.
“We will see how Brendan is today and tomororow, but if he’s not right then Josh Lelan will start, as I thought he was excellent on Tuesday night,” said Wilder.
“It is difficult when you’ve not played any first team football for a lot of the season just to get chucked back in there, but I thought he did well.
“His attitude has been good and I thought he grew into the game with his performance on Tuesday night.”
The Cobblers secured their first win in five matches in midweek, ending a run of four straight draws, and Wilder was delighted with the attitude of his players, who had secured the Sky Bet League Two title at Exeter City three days earlier.
“On Tuesday the group never showed any sign of anything else other than being totally committed, and I thought our play was outstanding,” said the Cobbelrs boss.
“We got punished for one mistake and the boy stuck the ball in the far corner from a free-kick, but apart from that it was an excellent performance in all aspects of the game.”
