New-look Chesterfield welcome Oldham
Chesterfield boss Gary Caldwell could hand debuts to a number of new signings against Oldham.
Caldwell's second game in charge comes two weeks after his first, a goalless draw with AFC Wimbledon, and following five new signings.
Former Manchester United defender Sadiq El Fitouri could make his debut after signing until the end of the season, while Manchester City striker David Faupala and Preston midfielder Liam Grimshaw have joined on loan for the rest of the campaign and could also play.
Birmingham midfielder Reece Brown and QPR defender Osman Kakay, who have joined until April 30, could feature, but winger Gboly Ariyibi has joined Nottingham Forest and Liam O'Neil has left for Cambridge.
Oldham manager John Sheridan bolstered his attacking options late on in the transfer window and all three new loan arrivals are in contention.
Winger Chris Taylor joined from Bolton, another wideman Tope Obadeyi was reunited with Sheridan for the second time having arrived from Dundee while Burnley's Aiden O'Neill will add some dynamism in central midfield.
Striker Billy McKay has left after his season-long loan from Wigan was cut short but, importantly, Sheridan retained captain Peter Clarke despite a bid from Scunthorpe and the player's desire to move.
Midfielders Lee Croft and Darius Osei, both out since early January with hamstring injuries, could also be in line for a return.
