Celtic suffer rare defeat
It doesn't happen often, but no-one's perfect. Perhaps shaken by their recent Champions League exit, Celtic were beaten by Hibernian in the Scottish capital.
Josh Campbell broke the deadlock for Hibs inside 120 seconds and added to his tally just before the half-time break, putting his side 2-0 up after what was a fairly contested 45 minutes.
The second period was nothing short of Celtic dominance, however - but the reigning champions were thwarted by a professional midfield display by Hibernian.
It's worth pointing out Nicky Cadden, who was particularly impressive along Hibs' left side.
Daizen Maeda would eventually get among the goals for Celtic shortly after the hour mark - and the Japanese star thought he scored an equaliser in the 83rd minute, but it was chalked off after a VAR review.
The Celts host Aberdeen in their next match, which presents an opportunity for Brendan Rodgers' men to make up for their shortcomings and take a step closer to the Premiership title.
For Hibernian, they're up against Dundee Utd in their next outing.
Rangers fail to capitalise
Though the Premiership title 'race' may now be more of a 'chase', Rangers still threw away a golden chance to close the gap on Celtic.
With news of the Celts' defeat to Hibs surely reaching the dressings rooms before kick-off, Rangers could have put a jolt of worry in the minds of their bitter rivals.
But the Gers were off the boil and were struck down by a more clinical St Mirren side at Ibrox to the tune of 2-0.
Rangers had the lion's share of possession, but - as has been a thorn in side of Philippe Clement's men before - they just couldn't find the back of the net.
Up next in the league for the Glaswegians is a short trip to Kilmarnock, who aren't enjoying the liquid type of football they were employing last term.
For St Mirren, they face Hearts in what should be a great battle - win or draw and the Saints will at least stay in the top six; lose and they could fall as far as tenth.
Hearts skip over Killie and co.
Hearts were able to overcome an improved St Johnstone 2-1 in Perth to leapfrog top-six rivals Motherwell and Kilmarnock.
Lawrence Shankland and January loan-signing Elton Kabangu proved to be a dynamic duo, with the Scot setting up the Belgian twice for the Jam Tarts' goals.
Kabangu opened the scoring in the first period, before St Johnstone were able to pull one back through Adam Sidibeh in the second.
Despite playing well, any hope of a Saints fight-back was dashed just four minutes later as Kabangu would latch onto another Shankland assist to bag the match-winner.
As mentioned further up, Hearts will take on St Mirren in their next match - with an eye to leapfrog another top-six rival.
For St Johnstone, they will next host Ross County. It's a match they need to win if they're to climb up the table, but the Staggies are in a fine run of form (two wins and a draw from their last four games).
