Gary MacKenzie has completed a permanent move to Blackpool from League One side MK Dons for an undisclosed fee.
The 27-year-old defender, who made 12 league appearances for The Seasiders on loan last season, has agreed a two-year contract, with an option for a further year.
"It's good to have it all tied up now and be able to focus on the new season," MacKenzie told the official website. "I'm just looking forward to getting out on the training pitch with the boys again and planning for the start of the season.
"I enjoyed my time here last season and the three months that I had here were pretty good. It gave me a wee taste of Championship football and it kind of made my mind up of where I wanted to try and play. I've been given the opportunity to come here and do that so hopefully I can do well," he added.
MacKenzie, who has been handed the number five shirt, will discuss his move back to Bloomfield Road in-depth later this afternoon.
