The 23-year-old defender spent the season on loan at Port Vale and AFC Wimbledon and is set for a permanent exit from Selhurst Park.
He is not part of Crystal Palace’s plans going forward and the club have been ready to move him on in the next transfer window.
And it has been claimed that a deal is close to getting worked out for Balmer to leave Crystal Palace in the summer.
St. Mirren are close to signing him after tabling a bid worth £75,000 for the Eagles centre-back ahead of the transfer window.
Balmer is expected to go north of the border, thus Crystal Palace is willing to accept the offer and sever connections with him.
The centre back will continue his career in Scotland after the transfer window opens in the summer, and the transaction is anticipated to go through.
Balmer joined Crystal Palace in 2022, although he never played for the team. He is now expected to leave Selhurst Park.
