Port Vale manager Michael Brown says he will be interested in bringing Callum Guy back on loan once the midfielder is fit again.
Brown says he is waiting for the 20-year-old to fully recover from a hamstring problem which brought his loan spell at Vale Park to an end last season.
Brown told the media: “Callum is still injured and is maybe back in a week or two.
It turned out to be a really long injury. We are still talking to Gary [Rowett] and Callum and we will see where that one goes.
“We are in Derby and Callum’s hands but we will see where that one heads.”
