Caley Thistle’s miserable start to the Championship continued as they suffered a 2-1 defeat at Dumbarton.
Captain Gary Warren was sent off on a day to forget for the Highlanders and the result leaves Inverness with four points from their opening seven matches.
Wales international Owain Fon Williams made his first appearance for manager John Robertson and his first since April.
The goalkeeper was one of four changes made from the side which lost 3-1 at home to Livingston a week ago with Carl Tremarco, Coll Donaldson and George Oakley replacing Mark Ridgers, Alex Cooper and John Baird, who dropped to the bench and David Raven who missed out due to illness.
Inverness arrived at Dumbarton Football Stadium in sore need of a win following a start of just one victory in their opening six matches in the Championship and they got off to a perfect start by taking the lead in the eighth minute.
Liam Polworth strode forward from midfield before playing in Connor Bell and the attacker turned a Sons defender before running into the box and firing past Dumbarton goalkeeper Scott Gallacher.
The visitors had opportunities to add to their tally before the break with the best chance falling to Bell but Gallacher managed to block the forward’s attempt after he had again ran clear on to a Polworth pass.
Those missed chances kept Dumbarton in the game and they equalised at the beginning of the second half when poor defending allowed Dimitrios Froxylias to collect a flick-on in the box before firing the ball high past Fon Williams.
It got worse for the visitors as Dumbarton swept into the lead just after the hour mark.
Fon Williams did brilliantly to keep out Froxylias’ 25 yard free kick but Sam Wardrop reacted quickest to fire the loose ball into the net.
Caley Thistle’s day went from bad to worse when captain Gary Warren received a second yellow card for simulation after going down in the box under a challenge from Sons defender Andy Dowie.
