The players in question are goalkeeper Ayden Duffy, defender Frank Sinclair, midfielders Owain Warlow and Martin Pembleton, and forwards Ben Wright, Gary King and Geoff Horsfield.

Goalkeeper Ayden Duffy graduated through the Imps’ youth system but has failed to dislodge Rob Burch from between the sticks. Former Chelsea defender Frank Sinclair moved to Sincil Bank last summer following his release from Huddersfield Town.

The Imps’ manager Peter Jackson allowed Sinclair to join Wycombe Wanderers on loan in March, having played 24 times for Lincoln, and was deemed not to be part of the Lincoln’s future plans.

Midfielders Owain Warlow and Martin Pembleton both graduated through the club’s youth system but have failed to make an impact this season. Pembleton spent the latter half of the season on loan at Lincoln United.

Geoff Horsfield joined the Imps in January following his recovery from testicular cancer. The veteran striker scored just one goal in 17 appearances since his arrival, which was not good enough to be given a new contract. Youngster Gary King has struggled to make a first team impact this season and spent a spell on loan at Boston United.

Ben Wright is the last player to be shown the exit door. Wright joined the Imps in the summer of 2007 from Viking, a Norwegian club. He finished top scorer for the Imps in his first season with 15 goals, but has struggled this time.

Meanwhile three of Peter Jackson’s out of contract players have been offered new ones. Frenchman Dany N’Guessan and forwards Sam Mullarkey and Adrian Patulea have been given the opportunity to remain at Sincil Bank for the next season.

The club also offered a new contract to defender Lee Beevers earlier this year. However, it still remains on the table.
