The Whites looked to be heading out in normal time following Mallik Wilks' fifth-minute strike only for Gjanni Alioski to equalise in the 92nd minute to take the game to spot kicks.
Yet United's joy and relief was shortlived and Graham Smyth, the YEP's chief football writer, hands out the scores.
7. Ian Poveda
7 - A livewire with the ball. Some lovely runs. Couldn't add an end product but he was Leeds' best outlet and the only one to look likely to unlock Hull. Picture by Tony Johnson.
8. Mateusz Bogusz
5 - A couple of nice runs that gave Leeds a brief threat but couldn't get to grips with the game in midfield. Picture by Phil Noble/PA Wire.
9. Tyler Roberts
5 - Drifted through the game. Marcelo Bielsa implored him to move more but he just couldn't get into it. Picture by Oli Scarff/PA Wire.
10. Gjanni Alioski
6 - A frustrating first half. Slightly better second half and got the equaliser but not one of his better performances. Picture by Tony Johnson.
11. Rodrigo
5 - Largely ineffective. Looked frustrated, very little of what he tried came off. Came deeper looking for the ball so Leeds didn't have a focal point for the attack. Picture by Oli Scarff/PA Wire.
12. Pascal Struijk
6 - Solid on the ball and in defence. Couldn't solve the Wilks problem but did give Leeds more presence. Photo by Phil Noble - Pool/Getty Images.
