Carlisle United manager Graham Kavanagh plans to rest some of his players after playing and training on "heavy pitches" contributed to
The Cumbrians looked to have secured a point thanks to an overhead kick from Lee Miller on the stroke of half-time.
But Millers winger Kieran Agard's 92nd minute goal left Carlisle just four points above the League One drop zone.
"The group looked jaded and need a few days off. Late on, some of them were dead on their feet," said Kavanagh.
"That's understandable because the pitches we've trained on haven't been great. It was then a heavy pitch for the game - it's been difficult."
Experienced former Rangers striker Nacho Novo made his debut as a late substitute on Saturday.
His availability comes as a boost after on-loan Aston Villa forward
"I had hoped to sign someone before the game but his club changed their mind. As a result, we lost the chance to keep Michael," Kavanagh told BBC Radio Cumbria.
"We have four loan players at the moment and really need some help in central defence. There's only Courtney [Meppen-Walter] and Sean O'Hanlon fit.
"With five being the maximum number of loans in a match-day squad, that may have to be the priority now."
