Blackman set for Caley comeback Andre Blackman could return for Inverness in the Clydesdale Bank Premier League match against Dundee United. The on-loan Celtic defender missed the midweek cup win over Inverness with an ankle injury. Owain Tudur Jones serves the final match of his three-game ban while Simon King (ankle), Chris Hogg (knee), Nick Ross (shoulder) and Shane Sutherland (leg) remain on the sidelines. Manager Terry Butcher has been offered a one-match touchline ban following his criticism of referee George Salmond after the recent 1-1 draw with Aberdeen. Butcher was unhappy with the sending-off of Tudur Jones and felt his side should have been awarded a second penalty in the Clydesdale Bank Premier League game on September 15. Butcher has been accused of "making comments in a media interview which criticise a decision of the referee in such a way as to indicate incompetence", according to the Scottish Football Association`s compliance officer, Vincent Lunny. The former England captain has until next Wednesday to respond to the notice of complaint. United defender Brian McLean has recovered from a knock he suffered against Queen of the South. Recent signing Gregory Vignal will also be in the squad but is not expected to start. Winger Gary Mackay-Steven is still sidelined following knee surgery. Manager Peter Houston believes their Scottish Communities Cup League win over Second Division Queens was the ideal preparation for the trip. United had to fight hard to secure a narrow 1-0 win on Tuesday where they had to survive a late onslaught before booking their place in the last eight. And Houston reckons their tough test in Dumfries means they will be ready for anything Butcher's men can throw at them when they hit the road to the Highlands for another away fixture. Houston said: "It was a very tough 90 minutes the other night which we did well to come through. "We were pushed all the way and had to show a lot of resilience which is what you have to do when you go away from home in the cup. "Now we're looking forward to another demanding game against Caley Thistle when we'll have to display the same kind of commitment. "I've no doubt the lads will dig deep again as they proved on Tuesday because it's never an easy game against Inverness. "Terry Butcher will have them well prepared and motivated as always which is what you'd expect from his team. "We'll have to be right up for it from the start as we were at Palmerston as it's a difficult venue at the best of times."
