The Imps have completed the signing of experienced forward Chris Maguire on a two-year contract.
The 32-year-old, who was a free agent after his contract expired at Sunderland, adds valuable experience and leadership skills to Michael Appleton’s squad.
The Scotland international is reunited with manager Appleton, who previously took him to Portsmouth and Oxford United.
Appleton said: “He brings us a lot of quality in two or three positions, he is very experienced so will help the group in difficult moments throughout the season.
“He is a leader who brings some real knowhow, he will really help the young players in the group and help bring a balance to the squad.”
Maguire becomes the Imps’ second signing of the summer after the arrival of Lewis Fiorini on a season-long loan from Premier League side Manchester City.
Appleton added: “Lewis is a very dynamic player who will enhance our squad. He is a strong runner with and without the ball, he has a great range of passing which I'm sure will excite our fans.”
