SPL - Round-up: Celtic and Rangers crumble
Goals by Ian Black and David Templeton gave a 2-0 Hearts victory over 10-man Celtic in a turbulent Clydesdale Bank Premier League encounter at Tynecastle which saw Hoops manager Neil Lennon sent to the stand.
Black gave the home side the lead with a deflected drive in the 28th minute and in the 56th minute he was crunched in a tackle by Joe Ledley to earn the Hoops midfielder a red card.
Two minutes later the Gorgie men scored a breakaway second through Templeton before Lennon was dismissed from the dugout by referee Craig Thomson after aggressively complaining about a Celtic penalty claim that was ignored.
Rangers suffered their first Clydesdale Bank Premier League defeat of the season going down 3-0 to Hibs.
The result saw Colin Calderwood celebrate his first win as manager of Hibernian.
The Easter Road side headed into the clash at Ibrox joint-bottom of the table and with few backing them to cause an upset but they stunned their hosts thanks to goals from Liam Miller, John Rankin and Francis Dickoh.
The victory took Hibs to eighth in the SPL, while Rangers were able to retain their single-point advantage at the summit after Celtic's defeat.
Nick Blackman struck a first-half hat-trick to consolidate Motherwell's place in the top three of the Clydesdale Bank Premier League in a 4-0 win over St Johnstone.
The on-loan Blackburn striker finished off two clinical attacks down Motherwell's right wing before converting from close range following Stevie Hammell's injury-time free-kick.
Blackman had not scored at Fir Park but his treble, on the eve of his 22nd birthday, took his tally to eight SPL goals in 10 starts and John Sutton completed the rout with three minutes left.
St Johnstone have now conceded 13 goals in four consecutive defeats and, although they had their fair share of first-half possession, they had no answer to Motherwell's pace in attack.
Two clinical strikes from Michael Higdon saw St Mirren move off the foot of the Clydesdale Bank Premier League table with a 2-1 victory at Dundee United, their first away win of the season.
Higdon struck after 41 and 65 minutes as Saints claimed their first points on the road to deny United a third straight success.
Prince Buaben powered in an 86th-minute free-kick to set up a tense finale, but United suffered a third home loss of the campaign.
United were seeking to build on victories over Hibernian and Hamilton, but in a limp display failed to test Saints goalkeeper Craig Samson until Buaben's late strike.
A Conor Sammon double helped Kilmarnock to a 3-0 win over Hamilton Academical at Rugby Park.
Chelsea loanee Chris Gordon had given Killie the lead with his first goal for the club in the 34th-minute, before Sammon's second-half brace gave the home side their third consecutive 3-0 win.
