Colchester will check on the fitness of Welsh defender Christian Ribeiro (groin), with John White on standby.
On-loan Leeds midfielder David Prutton is ineligible, while Paul Reid and Ashley Vincent are injury doubts and Ian Henderson is suspended.
Leeds United manager Simon Grayson told BBC Radio Leeds:
"They are a very difficult side to play against and they've had great results in recent weeks.
"They are serious promotion contenders and they know if they beat us they can close in on us.
"We know what tactics we'll face and expect a tough game.
"But I think the players have had a bit of a kick up the back side of late and they are looking forward to righting some."
