Dundee United will be without midfield pair Calum Butcher and Jeando Fuchs for the Scottish Premiership clash with St Johnstone, which was rearranged for Tuesday night after a frozen pitch forced a postponement on Saturday.
Butcher is expected to return from a hamstring injury at Hamilton on Saturday, while Fuchs is waiting to discover the extent of a knee issue.
Marc McNulty and Ryan Edwards will return from injury, while long-term absentee Logan Chalmers is back running after his ankle lay-off.
Michael O'Halloran is suspended for St Johnstone.
The Saints attacker was sent off against Rangers on December 23 and will complete a two-match ban.
An unnamed player will miss out after testing positive for Covid-19.
