Joel Byrom has signed a new two-year deal to stay at the Cobblers.
Manager Chris Wilder opened talks with the former Stevenage and Preston North End midfielder earlier this week, and Byrom has wasted no time in committing his future to Northampton.
The 28-year-old initially joined Town on loan from Preston back in August, and then signed a short-term Sixfields contract in January after having his contract terminated at Deepdale.
Byrom has been a regular in the Cobblers side throughout the season, making a total of 41 appearances and scoring three goals.
He will now be at the club until the summer of 2017.
