Kilmarnock goalkeeper Cameron Bell spoiled a fine performance by being sent off as Inverness emerged with a 2-1 victory following a breathless Clydesdale Bank Premier League encounter at Rugby Park.
The Scotland cap saved a penalty from Graeme Shinnie just before half-time when the visitors were leading through Andrew Shinnie's 22nd-minute strike.
Killie midfielder Liam Kelly levelled in the 56th minute with a wonderful drive from distance but when the impressive Bell saw red for a foul on last man Ross Draper, it allowed Billy McKay to slam the penalty past substitute keeper Kyle Letheren.
