Millwall have suffered a blow with the news Paul Robinson will undergo another operation on his metatarsal.

The defender suffered an awkward fall in training in which he "rocked" his already operated toe, although a subsequent X-ray and two scans have shown no break.

However, there are concerns that the internal screw in place has been damaged or moved which could provide complications in the future.

With the start of the season almost four weeks away, the Lions have opted to operate on Robinson to replace the screw with a high density version.

It is unknown how long the 27-year-old will remain on the sidelines, although club physio Bobby Bacic will know more following the procedure.
