The injury was picked up right at the end of training today when Adam went to turn a shot from Mills towards the net.
The Millers staff placed the ankle in ice and applied compression immediately, tomorrow they hope to have more idea as to the extent of the injury.
Both Sharpes and Fenton, are looking likley to be available, as does Micky Cummins and Tom Pope. Nicky Law is still feeling some pain in his toe.
