Young midfielder misses Rochdale trip
A crunching tackle against Bristol City has seen the midfielder miss the past two fixtures, and he will also miss Saturday's game at Rochdale.
The U''s will once again be without Tom Lasplie this weekend.
Boss Tony Humes has no other injury problems and had added Kenny McEvoy and Jamie Harney to the eighteen that faced Notts County on Tuesday night.
The U's are still without the services of long term injuries but Tosin Olufemi is back playing U21s games and Frankie Kent should join him in the next week or so.
U's: Walker, Lewington, Wynter, Briggs, Harney, Eastman, Osborne, Gilbey, Lawrence, Fox, Moncur, Massey, Sembie-Ferris, Szmodics, Hewitt, McEvoy, Marriott, Healey, Porter, Bonne.
