He will be able to play - for Derby! The match is not until Nov.4 and it's only a month's loan. Also he played against Lincoln in the 3rd round, and even if he hadn't, Derby would hardly let him star against them and get himsolf cup-tied in thje process!
More thought needed before posting I think, Dirty Dave.
I have always rated him as a player, not as dirty as many people would have you believe, the sort of player you love to have in your team but hate to see play against you. Shrewd move, should add bite to the midfield, he can make mincemeat of this division.
