Turner was forced out of Saturday's dramatic 2-2 draw against Middlesbrough with knee and ankle knocks while full-back Hall also picked up a knee problem.
Elliott Ward and Patrick van Aanholt were the two players to replace them and it remains to be seen whether manager Chris Coleman will go with the pair again.
Isaac Osbourne overcame a knee injury in time to face Boro and he will again be hoping to keep his place in midfield, despite coming off for Aron Gunnarsson at half-time.
Defender James McPake (shoulder) and midfielder David Bell (ankle) remain long-term absentees.
