Adam Jackson says he feels right at home after committing his future to the Imps until the end of the 2024/25 season.
The centre-back moved to Lincolnshire from Scottish Premiership side Hibernian in August 2020, and is pleased to have extended his stay for at least another two seasons.
He said: “I’m delighted to get it signed and commit my future to the club - I’m absolutely buzzing to stay.
“I feel really settled here. I love the city and club, I work with a great group of people every day and there was never any reason to look elsewhere.”
