Ross County beat Rangers 3-2 in Sunday's cinch Premiership match to earn their first ever victory over the Ibrox club and boost their hopes of avoiding the relegation play-off.
Rangers led at the break through a Jack Baldwin own goal but Simon Murray and George Harmon struck early in the second half and Josh Sims added a third goal in 69 minutes.
James Tavernier pulled one back with a late penalty but Rangers remain four points behind leaders Celtic going into Wednesday's rearranged fixture against Dundee at Dens Park.
