"Gareth will have treatment for the next couple of days - he won't do any running - and we'll see how he is on Saturday," said Dickens.
"The same applies to Martin. He's got a bit of a calf strain and he'll just have treatment and he'll not train this week. Like Gareth, he's 50-50."
Defensive duo Byron Webster (ankle) and James O'Connor (knee) will remain on the sidelines but midfielder John Spicer should return after missing the Coventry clash due to an unnamed injury.
