MARC Richards is expected to resume full training today after a minor hamstring problem.
The Spireites frontman felt the problem in training last Friday and was put through a fitness test a couple of hours before the 2-0 win over AFC Wimbledon the following day.
He passed, but the former Barnsley man managed only around 20 minutes in the match before leaving the field, Jack Lester took over.
Lester scored Chesterfield’s second goal after being teed up by fellow sub and scorer of the opener, Armand Gnanduillet.
Paul Cook will have to decide whether to go with Richards as a loan striker or stick with last week’s substitute duo.
The manager has clearly indicated he’ll not risk Richards unless he’s 100 per cent fit but if he fails to make it, neither Lester nor Gnanduillet are likely to be played as a lone striker, so a 4-4-2 formation would almost certainly be implemented for Saturday’s trip to Rotherham United.
Richards apart, Tendayi Darika (hernia) is Cook’s only injured squad member.
Mark Randall, who had a forgettable loan spell with The Millers in 2010-11, stepped in to fill his role last week.
Hull loanee Conor Townsend will be hoping to get a chance at the New York Stadium.
Spireites boss is still hoping to be able to bring in a left winger.
A three month deal signed tomorrow will take any new face beyond the play-off final, making any potential deal much more attractive to all parties.
Eleventh-placed Chesterfield are currently four places and six points behind their South Yorkshire neighbours in League Two.
