I have no evidence , so just pure speculation. Does the 28 day extension on Miles' loan and the fact he can play in the cup suggest he will sign permanantly. The extension gives us a few days to sort this out and he does not have to go back in the meantime. Also, I see Nathan Doyle is back at the club? Is he still in Keith Hills plans or is his move just a matter of time?
I think Preston only has a temporary management team in charge, so I guess they aren't in a position to do anything.
