Liam Marrs has returned to Boston United - but Duran Reynolds and Chris Dickinson have both left the club.
Defender Marrs played 13 matches for the Pilgrims last season while on loan from Sunderland.
He left the Black Cats towards the end of last season and, after overcoming injury, he has found himself a free agent.
This afternoon Marrs agreed a deal which sees him making a permanent move to the Jakemans Stadium.
However, Reynolds and Dickinson have both ended their stays with Boston.
Reynolds, who signed in the summer, has had his contract terminated by mutual consent after making three starts for the Pilgrims.
Dickinson scored on his debut as the Pilgrims kicked off their campaign with a 2-1 victory over Barrow.
However, the non-contract forward has left to find a club closer to his home in the north east.
