Brady doesn't rule out signing another free agent - but only if they are the right fit
Striker Jones joined on short-term deal earlier this week
Jon Brady would only consider signing another free agent if he was absolutely sure they were the right fit and would aid Cobblers' fight for League One survival this season.
Striker Alex Jones became Brady's first signing on Tuesday when he penned a short-term contract until the end of the season.
There are a couple of available spots in Town's squad should Brady want to strengthen further, but whilst he didn't rule out the possibility, he would be wary of upsetting the dynamic within the group.
He said: "Right now, the squad are giving everything they've got and the atmosphere within the group is very strong.
"If we were to bring somebody else in, we would have to be certain that it's the right character to help our cause a thousand per cent."
Jones was an unused substitute against Plymouth Argyle on Tuesday but Brady says he could be fit enough to play some part this weekend despite six months out of the game.
"Alex is a goalscorer but like a lot of footballers out there who are unattached, it's a desperate situation," added Brady. "It's not an ideal world.
"He's gone six months without playing so we're trying to give him training sessions where he'll get that sharpness which you need, especially as a number nine.
"We're doing all we can so that if we give him pitch time, he can only benefit us. We're haven't got loads of time but we've got to try and get the balance right so he's ready to go.
"It might only be 10 minutes or it might be 20 minutes and we can build on that. His work ethic and his desire towards getting fitter every day is there, we wouldn't have taken him on if it wasn't - he's a fantastic lad."
