Centre-half Callum Howe leaves the Imps as he joins fellow League Two side Port Vale for an undisclosed fee.
Howe joined the Imps in July 2015 after impressing during a trial period, and went on to make 36 appearances during his time at Sincil Bank, including eight during last season's title-winning campaign.
We would like to thank Callum for his service, and wish him the best for the future.
