Dagnall eyeing Orient start
Chris Dagnall is set to make his full Leyton Orient debut against Coventry.
The striker came on as a half-time substitute at Crewe last weekend following his switch from Barnsley and scored both Orient's goals as they came from behind to win 2-1.
Top scorer David Mooney is close to returning from a spell out with a foot injury but fellow forward Shaun Batt remains sidelined by a hamstring problem, although he has stepped up his training.
Midfielder Marvin Bartley (back) will be checked over while Eldin Jakupovic continues in goal with Jamie Jones recovering from a back injury.
Coventry will again only be missing forward Callum Wilson.
Wilson has been on the sidelines since he dislocated his shoulder on New Year's Day and he is not expected to return to action until March.
Sky Blues captain Carl Baker admitted the players were "absolutely shattered" after Friday's 4-0 defeat at Arsenal in the FA Cup but he expects them all to be fighting fit for another big game.
There have been no further bids for wantaway striker Leon Clarke and he is set to lead the Coventry line again as they aim to extend their unbeaten league run to six games.
