Hibernian 1-0 Aberdeen - Porteous heads only goal in Maloney's first game
St Johnstone 1-2 Ross County - Butterfield cancels out Charles-Cook opener; Callachan misses from spot but scores after break
St Mirren 0-0 Celtic - League Cup winners six adrift after being held
Premiership managers will be getting questioned on whether the winter break should be brought forward, but what do you think?
Thumbs up if you feel the league should continue as normal throughout the festive period, thumbs down if you want the winter break to come in after tonight's action...
St Johnstone v Ross County (19:45)
Ross County manager Malky Mackay makes three changes to the side that drew 1-1 with Livingston last time out.
Keith Watson, Ross Callachan and Joseph Hungbo are all in from the start for the visitors.
Connor Randall, Jordan Tillson and Dominic Samuel all drop to the bench for the Highlanders this evening.

St Johnstone v Ross County (19:45)
St Johnstone boss Callum Davidson is without forwards Chris Kane and Eetu Vertainen who are isolating, while keeper Zander Clark and right-back Shaun Rooney are also out of the matchday squad for St Johnstone.
Midfielder Liam Craig drops to the bench for the Premiership's bottom side.
Murray Davidson has missed recent games for the Perth side but is back in from the start this evening. Michael O'Halloran, Lars Dendoncker, Jacob Butterfield and goalkeeper Elliot Parish also come into the starting line-up.

Hibernian v Aberdeen (19:45)
The big news for Aberdeen is midfielder Scott Brown is out. And, with another ex-Hibee Dylan McGeouch also not in the squad, that leaves the Dons short in the middle, with Dean Campbell handed a start as manager Stephen Glass makes two enforced changes from the win over St Johnstone 10 days ago.
Ross McCrorie is suspended, which makes defender Declan Gallagher's return a timely one. The former Motherwell skipper hasn't played since being injured in a 1-0 win over Hibs at Pittodrie in October.

Right-back Calvin Ramsay was also injured in that game, and he is back in the squad, although only on the bench.
Teddy Jenks came on as a substitute to score the winner against the St Johnstone, but it has not been enough to oust Jay Emmanuel-Thomas from the starting line-up, who he has replaced from the bench in the last two games.
Hibernian v Aberdeen (19:45)
Scott Allan makes his first start since October as Shaun Maloney names his first line-up since taking over as Hibernian manager.
Midfielder Allan is one of three changes from Sunday's League Cup final defeat to Celtic, with winger Chris Cadden and full-back Josh Doig also starting.
Lewis Stevenson and Jamie Murphy drop to the bench, while Joe Newell doesn't make the squad after picking up a late yellow card at Hampden.
Kyle Magennis, Melker Hallberg and Sean Mackie have been nursing injuries and none of them make the squad either.

The visitors can close the gap on the play-off spots, while Stewart Petrie's men will be looking to put some pressure on leaders Cove Rangers.

A win for the hosts would see them move within four points of Elgin City in ninth, while Gary Naysmith's side can jump into fourth with a win.
Image source, BBC SportMust say, before the team news was announced, I wasn't expecting Celtic to make more changes than St Mirren...
St Mirren v Celtic (19:45)
Manager Jim Goodwin brings winger Jay Henderson, midfielder Dylan Reid and goalkeeper Dean Lyness into the starting line-up, and 17-year-old striker Kieran Offord makes his first-team debut from the start.
Midfielders Alan Power, Jamie McGrath and Ryan Flynn, plus keeper Jak Alnwick are all out of the matchday squad as St Mirren deal with a Covid outbreak.
No player on the St Mirren bench has made a first-team appearance so far.

St Mirren v Celtic (19:45)
Hampden match-winner Kyogo Furuhashi and goalkeeper Joe Hart are absent as Celtic change more than half their team from Sunday's League Cup final triumph over Hibs.
Also dropping out of the squad are Carl Starfelt and the injured David Turnbull, while full-backs Greg Taylor and Josip Juranovic make the bench.
Scott Bain mans the goals, nineteen-year-old striker Owen Moffat is handed a first start, while Anthony Ralston, Liam Scales and Stephen Welsh slot into defence and Nir Bitton replaces Turnbull in midfield.

Shaun Maloney makes his managerial debut with Hibernian, who welcome Aberdeen to Easter Road.
League Cup winners Celtic look to close the gap on leaders Rangers away to a Covid-hit St Mirren.
And finally, bottom club St Johnstone go to battle with Ross County in a huge game at the foot of the table.

We got the news earlier that the Scottish Championship, plus Leagues 1 and 2, have opted not to shut down amid the spike in Covid-19 cases.
All lower league games will continue throughout the new government measures, which will see crowds capped at 500.
We are still awaiting a decision on the Premiership and we will update you with that as soon as it comes through.
In the meantime, feel free to click here to read all the details of tonight's vote.
In normal circumstances, we would be buzzing about tonight's rearranged games kicking off a festive feast of Scottish football.
But it all feels a bit strange now, doesn't it? Regardless, we have three Premiership crackers this evening.
It may be the last top-flight action we get to enjoy for a few weeks, so let's make the most of it.
Here we go...
