Inverness manager Terry Butcher has criticised the SFA's appeal process after deciding not to challenge a red card given to Owain Tudur Jones.
Tudur Jones will serve a second two-match ban of the season following his dismissal in Saturday's 1-1 Clydesdale Bank Premier League draw with Aberdeen.
Butcher said: "After giving the matter a great deal of thought, we have decided against lodging an appeal against Owain's sending off.
"This isn't because we think the red card was fair, because we certainly don't. But it doesn't make sense for the club to spend ?1,000 on an appeal when the odds are stacked against us.
"We would have to prove the referee guilty of making a mistake rather than simply defending the innocence of our player.
"This procedure has worked against us in the past. Last season we appealed four times and only once, Greg Tansey against Celtic, was it upheld.
"The whole appeal process is far from ideal and, taking all things into consideration, we now accept that Owain must serve his suspension."
Tudur Jones is now scheduled to miss the SPL meeting with Hibernian and the Scottish Communities League Cup tie at Stenhousemuir.
Meanwhile, Butcher fears the worst over a knee injury Shane Sutherland sustained against Aberdeen.
The Caley Thistle boss said: "Shane will have a hospital scan on Tuesday on his right knee to assess the extent of the damage.
"We keep losing key players and this looks like being another blow."
