The 30-year-old was handed his marching orders in just the 14th minute after being adjudged to have taken down Tom Bradshaw in the box. Jed Wallace duly converted before Bradshaw himself struck. Gjanni Alioski bagged after the break but United were unable to earn anything from the tie. Here's how we rated the performance:
1. Luke Ayling
7 - Overcame some early rust to slot in really well in the centre of defence. Battled well.
2. Gaetano Berardi
5 - In allowing Bradshaw to get away from him he created the situation that led to the penalty and sending off, even if replays showed neither decision to be correct.
3. Ben White
8 - Really stepped up in the absence of Cooper and, after 14 minutes, Berardi. So comfortable on and off the ball with few mistakes.
4. Gjanni Alioski
7 -Good first half. Half-time change allowed him to get forward, took his goal well. Worked hard throughout.
5. Kalvin Phillips
7 - In a game that called for physicality, he provided it for Leeds. Some big tackles. Kept his composure. Distributed well.
6. Mateusz Klich
7 - Tidy and clever in his work on the ball, whether deep in his own half helping Leeds to break out or in attack.
