Northampton have been given a boost after their relegation to National League One with centre Jon Clarke signing a new three-year contract.
Clarke suffered the injury at the start of the season against Newcastle
The 23-year-old Yorkshireman has pledged his future to the club despite interest from a number of Premiership sides, says BBC Northamptonshire.
Clarke had a year left on his contract and has scored 14 tries in 55 games.
He had limited chances last season after breaking his ankle in the opening game of the Premiership season.
He returned for the last two games of the Premiership campaign and the Heineken Cup semi-final against Wasps.
"Obviously it was a hard season for me after the injury and not being able to help the lads on the field," said Clarke.
"But the club stood by me and the medical team were brilliant throughout my rehab.
"I'm looking forward to helping get Saints back to the Premiership at the first attempt and then to the top of English rugby."
