A reshuffle to the Gillingham team may be required by manager Andy Hessenthaler after a gruelling last few weeks.
A tough fixture schedule is starting to take its toll on his players and a long trip to Plymouth on Saturday awaits.
"There were a few out on their feet (on Tuesday)," said the Gills boss (pictured).
"It's understandable because there have been a lot of games and so I need to think about my team selection for the weekend, in respect how people are feeling."
The players had Wednesday off to recover but were back in training on Thursday and set off for Plymouth on Friday.
Hessenthaler's squad is also feeling the effects of a bug that left both Joe Martin and Garry Richards sidelined in the week. Young defender Connor Essam was also feeling ill but managed to last the 90 minutes against Hereford.
The Gills manager is unlikely to be able to call on any of his injured players, although some are getting close.
Midfielder Danny Spiller lasted 60 minutes of a practice match at the training ground on Tuesday and Andy Frampton is also recovering well from an ankle injury.
Frampton said: "The good news for me is that the injury is better than I first thought.
"I was expecting to be out for a while but it's progressing nicely."
