Hird won't be seen for Spireites
Sam Hird is suspended for Chesterfield as they prepare to host bottom-of-the-table Leyton Orient.
Hird was sent off after only three minutes of the defeat to Preston and will serve a one-match ban on Saturday. In his absence, Charlie Raglan will be recalled to partner Ian Evatt in central defence.
After playing almost the entire game with 10 men in midweek, Blues boss Paul Cook may opt to freshen things up elsewhere. The likes of Ritchie Humphreys, Mark Duffy, Ollie Banks and Mani Dieseruvwe could come into his thinking.
Big striker Armand Gnanduillet will be assessed after struggling with an ankle injury recently but winger Gary Roberts (hamstring) remains unavailable.
Dean Cox could return to the Orient starting line-up.
The winger was unwell in midweek and only considered fit enough for a place on the bench against Notts County, although he came on for the final half an hour of the 1-0 defeat.
Marvin Bartley and Jobi McAnuff were also among the substitutes on Tuesday night following spells out injured leaving only Adam Legzdins, Jay Simpson and Lloyd James in the treatment room.
Orient's third straight defeat left them rock bottom of the table, six points from safety.
