Inverness midfielder Ross Draper is out of Sunday's Scottish Premier League clash with Motherwell at Caledonian Stadium.
Draper has still not recovered from the ankle injury he picked up in the recent win at Kilmarnock.
Simon King (ankle), Chris Hogg (knee), Nick Ross (shoulder) and Ryan Esson (hip) are still out.
Motherwell boss Stuart McCall is faced with major injury worries.
Illness within the Fir Park squad forced the cancellation of two training sessions this week, with only four first-team players deemed fit enough to take part.
Shaun Hutchinson came through a training session on Friday unscathed and may be considered for selection, however long-term absentee Steven Saunders (knee) remains sidelined.
