Cobblers injury latest: James Olayinka, Jordan Turnbull and Joe Martin
Keith Curle has given a health check on his squad ahead of Saturday's trip to Macclesfield Town with three players currently struggling from knocks picked up in recent matches.
Centre-back Jordan Turnbull suffered a problem during the FA Cup tie against Derby County last Friday before James Olayinka, who only signed from Arsenal on Monday, took a whack to his ankle in the latter stages of Tuesday's win over Scunthorpe.
"The more you see James play, the more you will see that he will have knocks, bumps and bruises every time he plays - but so will a number of the opposition," said Curle.
"He gets about the pitch and he wants to be hunting down the football and with that he'll pick up bumps.
"It's part and parcel of how he's going to play. It's something to be expected with him because he's a very competitive player."
Turnbull was said to have sustained a dead leg against Derby but further scans have revealed a muscle problem.
"Jordan picked up a slight strain in the first 20 minutes against Derby and managed to finish the game," Curle added.
"But then the adrenaline calms down so he's now gone for a scan and he's got a slight tear in one of his adductor muscles at the top of his hip.
"It's not an overly used muscle injury but it's something we need to monitor."
Joe Martin was unable to finish Tuesday's game after tacking a nasty bang to the head.
Curle continued: "Joe's a competitive player and no matter how many missing teeth or bent noses he gets, he will still compete for the ball in our box and in the opposition's box.
"That's what you get with Joe. He hasn't had the game-time he wants but that's down to the change of shape.
"But he's got the versatility to play in a number of positions and he can play at centre-back or as an advanced full-back and he's got a great left foot.
"Even though he hasn't been getting the minutes, that competitive edge is still there.
"We'll find out if those players are able to participate in training and if they can train, hoepfully they'll be available for selection."
