Ashley Grimes, Jordan Cook and Ben Purkiss are also absent, while forward Romaine Sawyers is on international duty with St Kitts and Nevis.
Colchester, playing their first game under new manager Tony Humes, are bidding to avoid a fifth straight League One defeat.

Josh Thompson is still out with a hamstring problem, but is said to be nearing fitness.
