Millwall striker Gary Alexander is waiting to discover how long he will be out of action with a heel problem.
The 30-year-old suffered the injury shortly after scoring the winner against Leeds last week and was forced to miss Saturday's victory over Colchester.
He is already certain to miss the next fortnight before the club's medical staff can assess the injury again.
"Gary has been playing through the pain barrier but the Leeds match triggered the bone spur on his heel to flare up," Lions physio Bobby Bacic said.
"We are going to put him in an aircast boot for two weeks and then review him."
