Leeds sent out what was essentially their under-23s side as under-23s boss Mark Jackson took charge whilst Whites head coach Marcelo Bielsa also looked on from the dugout.
United left with a 3-2 victory thanks to a Crysencio Summerville penalty, a Sam Greenwood free-kick and a late strike from Charlie Allen which proved the winner.
First team midfielder Adam Forshaw also made his return from his injury nightmare as a second-half substitute as part of a contest which saw United's away fans return to a game for the first time since February 2020.
Fresh from his trip to Nethermoor, the YEP's Lee Sobot hands out the player ratings.

7 - A hugely welcome return for a player who has had a torrid two years with injury. On at the hour and looked in very good shape in the CDM role. It will be step by step but looking good for the 29-year-old first teamer. Picture by Bruce Rollinson.
