Sonny Carey joined the Addicks in the summer of 2025 following the expiration of his contract at Blackpool.

The midfielder came through the Norwich City academy before enjoying a successful spell with non-League side King's Lynn Town, which earned him a permanent move to Blackpool in June 2021.

Carey featured 133 times for the Tangerines across his four-year spell and netting 11 goals from midfield during his final season at Bloomfield Road.
