Caley Thistle were held to a 0-0 draw against Queen of the South in a poor Championship encounter at Caledonian Stadium.
Chances were few and far between, with both sides lacking a cutting edge in blustery conditions, as Inverness were held to a second successive goalless draw.
The result extends Caley Jags’ unbeaten league run to 18 matches, however they are now three points adrift of leaders Ayr United.
John Robertson picked an unchanged side from the team that drew 0-0 with Ross County in the previous weekend’s Highland derby, keeping faith with the same starting 11 for the fourth successive match.
Queens started the brighter of the two sides, with Lyndon Dykes seeing his effort from the edge of the box comfortably held by Ridgers.
Although chances were few and far between in the first half, Inverness’ greatest threat came in a flurry midway through the opening 45 minutes. Aaron Doran saw a 25-yard strike beaten away by goalkeeper Alan Martin, before Carl Tremarco sidefooted wide after getting on the end of a delivery from fellow full back Shaun Rooney.
Both sides carried only intermittent threat at the start of the second half, with Queens’ Callum Semple heading over from Dobbie’s corner, before Sean Welsh saw a long-range strike whistle just over in his efforts to find a breakthrough for the hosts.
It was Queens who came closest to opening the scoring however, when Dobbie’s free kick clipped the top of the bar just after the hour mark, however neither side was able to find the killer touch.
