Doubts for Davis
Crewe boss Steve Davis has a handful of injury concerns to contend with ahead of Colchester's visit to Gresty Road.
Alex triumphed at in-form Doncaster in midweek, but victory came at a price with Kelvin Mellor, Byron Moore and Abdul Osman all sustaining problems.
Mellor is a doubt having taken a blow to the knee and suffered swelling, while midfielder Osman is once again troubled by his persistent ankle complaint following the Keepmoat Stadium encounter.
Moore is awaiting the results of an x-ray after the winger picked up an injury to his foot.
England Under-19 striker Max Clayton has returned to training following a groin injury but is unlikely to be risked by Davis at this stage of his recovery.
Fellow forward Ajay Leitch-Smith (ankle) remains sidelined alongside teenage winger Ryan Colclough (broken jaw), with the latter pencilled in for a return to training next week.
