Defender Dwayne Samuels has left Blue Square Bet Premier club Grimsby Town by mutual consent.
The 20-year-old joined the Mariners in August 2010 after impressing in pre-season matches.
Injuries restricted the former West Bromwich Albion right-back, who was on a two-year contract, to just 11 first team appearances.
Meanwhile, 22-year-old striker Charles Ademeno has been released after just one year at the club.
He too had suffered a number of injury setbacks and played only 12 league games this season.
