Leyton Orient will check on Ben Chorley ahead of the home game against Swindon.
The centre-half was left out of Saturday's draw at Bournemouth as a precaution due to a calf problem.
Elliot Omozusi returned from a hamstring injury to deputise and he could revert to his preferred position at right-back if Chorley is passed fit.
Midfielder Matthew Spring was carrying a slight knock on Saturday and was named on the bench, so he will be pushing to return to the starting line-up along with striker Alex Revell after Jonathan Tehoue was preferred in attack.
Adam Chambers missed out at the weekend with the badly gashed shin he suffered at Brighton last week and the midfielder is unlikely to recover in time.
Swindon will assess a host of players including key striker Elliot Benyon.
The deadline-day signing netted a late equaliser on his debut against Rochdale on Saturday but also left the pitch nursing a tight hamstring and will be assessed.
As will defender Aden Flint who also received a knock on his debut against Dale.
Goalkeeper David Lucas - last included in Town`s matchday 18 at the start of December - returned to full training on Monday and manager Danny Wilson will see how he reacts before deciding whether he is ready to be involved.
Defender Lecsinel Jean-Francois has missed the club`s last three games with a leg injury while striker Vincent Pericard (knee) has sat out of the last three. Both will be closely monitored although Tuesday is expected to come too soon, with the former expected to return sooner.
Young midfielder Billy Bodin (illness) missed out against Bournemouth with an ankle injury before illness ruled him out of Saturday`s 1-1 draw versus Dale. He should be okay to be in contention for the trip to Brisbane Road as Swindon go in search of a much-needed victory.
