Midfielder departs for 2021/22 campaign
Brett McGavin will spend the rest of the campaign with National League side King's Lynn Town.
The midfielder has penned a season-long loan deal with the Linnetts.
Brett made his Town debut in an EFL Trophy fixture at Colchester in November 2019 and has racked up a further 10 first-team appearances to date.
The 21-year-old also spent the latter stages of last season on loan at Ayr United.
