Atkinson has re-joined Icelandic Premier League side IBV Football Club.
Atkinson re-joined Spartans in October 2017 after a short spell with the Icelandic outfit, who have come back in for the former Carlisle United man with a full-time deal that was “too good to turn down” for both club and player.
Atkinson first joined Blyth in December 2016, initially on loan from SkyBet League Two side Carlisle United before joining permanently in early 2017.
He made twenty-three appearances this term, adding to the fifteen he made in his initial spell with the club.
Blyth manager Alun Armstrong was adamant the decision was out of his hands, telling the club`s official website: “He’s decided to make the move back to Iceland – we’ll never hold a player back from playing professional football.
“The deal is a good one for the player, and as a club as we’ve generated a substantial fee that will help us build towards next season.
“The offer was too good to turn down”.
