Town's longest serving player was forced to limp out after just 20 minutes of Saturday's clash against Derby County and tests have revealed he has suffered a strained hamstring, which although is nothing major, it may be enough to force him out of the clash at The New Den.
Speaking to the Official Club Website, Town Physio Dave Williams confirmed the news: "Bam Bam has strained a hamstring and could be struggling for Saturday. There is no tear so it's not a major injury but it's enough to make him a doubt for Millwall."
Should Naylor not make it, it's likely that John McGreal will partner Georges Santos in central defence for the blues.
