Late Ross County goal sinks Celtic
Ross County came from two goals down to claim a shock 3-2 win over runaway SPL leaders Celtic, while St Johnstone were 2-0 winners over Kilmarnock and the three others games ended all square.
Goals from Charlie Mulgrew and Gary Hooper had Celtic in command, but they were pegged back and a header from Steffen Wohlfarth in injury-time earned three points for the Ross County.
County's win win looked highly unlikely after 21 minutes after Mulgrew had scored direct from a corner and Hooper chipped home as goalkeeper Michael Fraser endured a nightmare six minutes.
But County also scored twice in six minutes. A stunning volley from Grant Munro and Sam Morrow's close-range finish got them level before the break. And the comeback was sealed when Wohlfarth beat Kelvin Wilson and Fraser Forster to a long ball to head into the net.
Second-half goals from Murray Davidson and Gregory Tade boosted St Johnstone's top-six aspirations as a one-sided clash with Kilmarnock ended 2-0 in Perth.
Davidson scored a 58th-minute opener and the home fans finally relaxed when substitute Tade rose to double their advantage five minutes from the end.
Dundee were left frustrated as Inverness struck late on through Billy McKay for a share of the spoils in a hard-fought 1-1 draw at Dens Park.
The home side's new interim manager John Brown was all set to celebrate his second win at the helm in the space of just a few days thanks to John Baird's excellent first-half opener but Caley Thistle hit back through McKay's 82nd-minute header.
Aberdeen were held to a 0-0 draw for the sixth time at Pittodrie this season as Motherwell became the latest team to frustrate the Dons.
St Mirren and Dundee United had to settle for a share of the spoils after a 0-0 draw in Paisley, in which John Rankin was sent off for the visitors two minutes from time.
