Boss Paul Lambert is hopeful that Corry Evans and Doneil Henry will be fit in time to face Rotherham United on Friday night.
Northern Ireland international Evans was substituted late in the 2-0 win over Bristol City with a slight groin injury, whilst Henry didn't make the trip to Ashton Gate due to a tight hamstring.
Also Darragh Lenihan, who was part of the first team squad that travelled to Bristol, has a slight back injury that will need to be assessed.
"Corry was feeling a bit of his groin but we hope he can train today," said Lambert.
"Darragh has got a bit of a back problem at the minute but hopefully it'll just be a couple of days for him.
"With Doneil, I think he was feeling the effects of training last week so that is why we decided to leave him here.
"We just had to watch that he didn't break down again, I think that is important.
"If he did break down we'd have to send him back to West Ham and that happened to him the last time. So we'll have to manage him to make sure that he is okay."
Tickets for the match will be on sale until the 7.45pm kick-off, priced from £13 for Adults, from £9 for Seniors and 18-21 year-olds and from just £4 for Juniors aged 17 and under.
