Villa boss Graham Taylor said: "He really shouldn't have been trying to sort the problem out himself. There are people on the staff readily available to have treated the problem.
"Darius tried to get the blood out himself, which he now realises was not really advisable. I am not certain he looks after his feet properly. It was giving him pain and it seems he used a medical implement to try to drill the nail.
"The outcome was it still caused him pain and was infected. He's now had half the nail removed and that's left him struggling to be fit for the Blackburn game. But he should be OK next week."
Stefan Moore could now be given another chance up front with Dion Dublin after partnering the ex Man Utd striker at Old Trafford when Vassell was ill.
