Defender Ollie Kensdale is set for a short spell on the sidelines with a thigh problem.
The centre-back went off at half-time at Yeovil Town on Saturday.
And Blues boss Kevin Maher confirmed he will be without the 21-year-old for this weekend's clash with Notts County at Roots Hall.
"We've got the scan back and it's good news in that Ollie is only going to be short-term," said Maher.
"We're hopeful it's only going to be for a couple of weeks and that he won't be out for as long as we first feared".
