Millwall will be without captain Paul Robinson during the busy festive period after the defender suffered a hamstring injury.
Robinson strained his hamstring during last Friday's 1-1 draw with Swansea City and was forced off after just seven minutes at the Liberty Stadium.
The 28-year-old, who has been a virtual ever-present for the Lions this season, is now likely to require three weeks on the sidelines.
It means the centre-half could miss Millwall's upcoming Championship games against Barnsley, Portsmouth, Leicester, Crystal Palace and Derby.
However, the Lions have received some positive news with midfielder Liam Trotter and striker Kevin Lisbie due to return to training this week after recent lay-offs.
