Boro fell a goal behind when Hull’s Allahyar Sayyadmanesh headed The Tigers ahead from a corner five minutes before half-time.
The hosts reacted well, though, scoring three times in a six-minute spell after goals from Hayden Hackney, Cameron Archer and Chuba Akpom.
Here’s how each Boro player fared at the Riverside:

Had to switch to centre-back late in the game after McNair’s withdrawal. Another impressive performance where he read the game well. 7 Photo: Alex Burstow
