Town are confident Alan Lee will be fit to face former club Cardiff City at Ninian Park a week on Saturday (KO noon). Lee limped off during the first half of Saturday's 6-0 romp against Bristol City.
Physio Matt Byard told the club site: "There are no major issues and we will let the achilles settle down.
"Alan will then undergo a programme of exercises and rehab next week and, at the moment, we are confident he will be OK for the Cardiff match."
