United initially signed Middlesbrough defender Jack Robinson on a half-season loan deal during the January 2023 transfer window.

He made eight appearances in all competitions, and became a permanent target, with a two-year deal signed and sealed in June 2023.

Robinson had been in the Championship outfit's academy system since the age of 13. He played twice for the Under-21 side in the EFL Trophy in October and November 2019 and signed his first professional contract with the club in the summer of 2020.

A regular at the heart of the defence in the under-23 team, he was named among the substitutes for the first team at Rotherham in April 2021. He made his senior debut as a late substitute against Wycombe Wanderers on 8 May 2021.

After extending his professional contract that summer, he made his first start for the senior side against Blackpool in the Carabao Cup in August 2021.

He joined National League outfit Yeovil Town on a season-long loan for the 2021/22 season and made a total of 18 appearances for the Glovers.
