Elliot Grandin has completed his return to Blackpool after signing a deal with the Sky Bet Championship club for the remainder of the season.
The 26-year-old midfielder moved to Crystal Palace in the summer, but made only one appearance for the Eagles and left by mutual consent last month.
Grandin only departed Blackpool last May after a three-year spell, but has headed back to Bloomfield Road in a bid to revive his career.
The Frenchman proved his fitness in a practice match on Tuesday and is available for selection ahead of Saturday's home match against Nottingham Forest.
Grandin scored six goals in 44 appearances during his first stay at the club.
