Callum Styles has returned to Barnsley following his loan at Sunderland AFC.
The Hungary international made the temporary switch to Wearside in January and made 12 appearances in red and white.
Kristjaan Speakman said: "As we continue to plan for the new season, we have decided not to take the option in Callum’s loan agreement and therefore his time with us has concluded. Callum’s attitude and application was first class throughout his time at the Club and we wish him well for the future."
All at SAFC thank Callum for his contribution and wish him well in the next chapter of his career.
