Davies has the power; Boxer Shorts.
St Helens man Davies (10-3-1) bids to reclaim the domestic bantamweight strap on the David Haye-Audley Harrison undercard on Saturday, November 13 at the MEN Arena.
Hall (9-0-1) won the title from Ian Napa in June before defending convincingly against Martin Power the following month.
But the ruler says Davies' record must be respected.
"Some of Gary's opponents haven't been great, but he must have a dig to put them away so he will be the hardest puncher I have ever faced," said Hall. "I have never been wobbled in my career, so I just have to box clever.
"My dream is to win the Lonsdale Belt outright. If I get over Davies, then one more defence and it's mine."
