Colchester will again be without goalkeeper Ben Williams for the Carling Cup trip to Hereford.
Williams picked up an ankle injury in pre-season and is expected to be out for another fortnight so Mark Cousins, who deputised in Saturday's 2-2 draw with Exeter, keeps his place.
Versatile defender Lee Beevers made his first appearance in almost year as a substitute at the weekend following a succession of injuries and he could start at Edgar Street.
Full-back Marc Tierney came through the 90 minutes unscathed following a calf problem and will be available again.
Midfielder John-Joe O'Toole remains a long-term casualty with the cruciate injury he suffered in April while defender Morten Knudsen is also out with a knee problem.
