SID NELSON will miss at least a month of action after breaking a bone in his foot.
The young centre back, who recently starred for the first team in a pre-season friendly against Stevenage, fractured a metatarsal playing for the U21s against Billericay Town last weekend.
Nelson's injury has frustrated manager Ian Holloway, who was not aware that the 18-year-old was playing in the game.
"I wanted him to play for the first-team in a practice game but unbeknown to me played for the U21s and broke his foot," Holloway said.
"I'm not very happy about that but such is life. He'll be out for a minimum of four weeks but it could be more than that if there's an additional problem.
"I wouldn't have played him in that game – I'd have played him in a training game amongst ourselves, so I think we've got that wrong.
"I didn't know he was playing because he was carrying a knock and I didn't think he was fit. I was delighted with how he played against Stevenage."
Meanwhile, Millwall are yet to receive an offer for either Danny Shittu or Paul Robinson.
The experienced duo have been told they are free to find new clubs this summer.
"There's nothing happening at the moment but there will be because they are too good for somebody not to take them," Holloway said.
"But if I get some injuries, I'd have no problem with either of those lads filling in. Danny is getting fitter all the time and Robbo is a great bloke."
