City have completed the signing of defender Tom Hamer on a three-year contract.
The 24-year-old joins the Imps from Burton Albion, where he made 147 appearances - scoring nine goals and assisting 17 times.
Hamer came through the ranks at Oldham Athletic and represented the senior team on more than 100 occasions before making the switch to the Sky Bet League One Brewers in 2021.
Tom said: “I’m really pleased to get the deal done. I been speaking to Jez George and Michael Skubala and I’m happy to get it over the line.
"I’m someone who works hard and give 100%. I am quite quick, decent in the air and also like to put a challenge in.”
Skubala added: “Tom is a player that really suits how we want to play as a defensive unit. He fits our profile for an outside centre back, he’s a great age, has played 200+ games and we also believe has plenty more to come in his development as a player.
"Tom is also a real warrior on the pitch, has an ‘old school’ defender’s mentality and a really useful long throw, which will give us another attacking threat.”
