NICKY Bailey has been ruled out of Millwall's midweek contest with Birmingham City and will undergo a scan on a suspected aggravation of a recent calf problem.
Boss Ian Holloway confirmed the blow prior to training on Monday morning.
Holloway revealed that Bailey would not take part in the session after he was on the end of a crunching tackle from Huddersfield's Tommy Smith at the weekend.
The Lions are unsure if Bailey has sustained further damage to his calf, which he tore during pre-season, or whether the midfielder has suffered a fresh injury.
"Bailey is having another scan today," Holloway said. "He won't be involved tomorrow."
