The move will see the right-back link up once again with former Whites boss Uwe Rösler on the Fylde coast.
Coyle, 21, has made a total of 22 appearances for Leeds since progressing through the Academy at Thorp Arch and makes the move across the Pennines in order to gain regular first team football.
Ahead of the loan deal, Coyle penned a new three year contract with the club, which runs until the end of the 2019/20 season.
