The boss hands a full debut to summer signing Fejiri Okenabirhie in one of ten changes to the side that beat Burton on Saturday...
The former Doncaster Rovers winger came on as a sub in United's Carabao Cup clash with Southamton a week ago, and tonight makes his first start for the U's since signing for the club in July.
Greg Taylor makes his second start for the U's since recovering from his long-term injury, returning to the side for the first time since beating Millwall at the start of the month.
Only Jubril Okedina keeps his place in the starting eleven.
Starting XI: Mannion, Haunstrup, Taylor, Brophy, O'Neil, Lankester, Okedina, Ibsen Rossi, Janneh, Okenabirhie, Simper
Subs: Holden, Williams, Ironside, Dunk, May, Knibbs, Worman
