Ryan penned an initial three-year contract at Ewood Park through to June 2028, with the option of an extra 12 months.

The 23-year-old became the second player to sign for Rovers this summer from Belgian club KV Kortrijk, following the arrival of winger Dion De Neve last month.

Alebiosu started his career with Arsenal, spending over a decade with the Gunners and signing his first professional contract with the London club in 2020.

He experienced his first taste of senior football during a loan spell with Crewe Alexandra during the second half of the 2021-22 season, before spending the 2022-23 season with Scottish Premiership side Kilmarnock, making 29 appearances across all competitions.

After leaving Arsenal, the full-back joined KV Kortrijk in September 2023 and went on to appear 25 times for the Jupiler Pro League club, before returning to Scotland, where he enjoyed a successful loan spell with St Mirren earlier in 2025.
