Defender Aden Flint has completed a move away from Bristol City to join Middlesbrough.
The 28-year-old, who scored 38 times for City, spent five years at Ashton Gate.
The 6ft 6in centre-back signed a new three-year contract in March after having helped City reach the semi-finals of the Carabao Cup.
Flint made 246 appearances for Bristol City and was the subject of much transfer speculation during the 2017 summer transfer window, with Birmingham City showing interest in the defender.
Flint signed for The Robins from Swindon town in 2013, helping them to secure a return to The Championship for the 2015/16 season.
