Millwall midfielder Nicky Bailey has been struck down with a third calf injury of the season.
The 30-year-old has started just once for the Lions in 2014-15 and now will have to wait on the sidelines again with a fresh calf problem.
"[Bailey] had resumed training but at the end of the week developed a small tear in his other calf," Millwall physio Bobby Bacic told the club website.
"Nicky is having the most wretched luck at present and although we do not predict this injury to keep him away from training for long he will need to play in the Under-21s before he can be considered for first team selection."
Bacic also confirmed that right-back Carlos Edwards is the Championship club's only long-term absentee.
