The most dramatic opening 45 minutes of today's Scottish Premiership games.

Aberdeen led through Luis Lopes' header but Liam Scales' red card for a second booking came after a foul in the box on Ryan Porteous, allowing Martin Boyle to level from the penalty spot.

A first half dominated by the hosts, but there were few chances other than Cristian Montano's goal. Stephane Omeonga had a few efforts early on, which he should have done better with.

Montano's header was too much for the returning Killie keeper Zach Hemming, with the left-back powering his header in from close range.

Kilmarnock, meanwhile, have mustered just one shot - that was blocked at close range. They need a much better showing in the second half if they are to get anything from this one.

All square in Perth at the break, no goals and very little between the sides. But this has been far from a dreary stalemate, both teams have had chances - as the bar and the post will testify.

Both teams also look good on the break, with the only thing missing that cutting edge in front of goal.

Maybe we will get it in the second half.

A bright opening in which both sides hit the woodwork, has given way to a bit of a battle.

Some neat enough play from both, but a lack of cutting edge.

Rangers lead thanks to an eight-minute strike from birthday boy Antonio Colak.

The hosts got off to a whirlwind start, with Ryan Kent and Scott Arfield spurning great chances before the breakthrough.

Dundee United have spent most of the game camped on the edge of their own penalty box but have had the odd glimpse of goal and Allan McGregor had to look lively to keep out a shot from Glenn Middleton.

Liam Scales is booked for his challenge, his second yellow card and the Aberdeen defender is sent off.

Liam Scales grapples Ryan Porteous to the ground from a corner and Hibs have a penalty.

The visitors still hold on to their early lead but they have their goalkeeper to thank. Elie Youan tests Kelle Roos with a long range effort that the goalkeeper tips over the bar.

Cristian Montano has scored his third goal of the season and his second in two games for Livingston. They lead Kilmarnock 1-0.

Anthony Stewart is yellow carded as he concedes a free-kick 30 yards from goal. Joe Newell, who scored last time out against Kilmarnock, tamely hits the free-kick into the arms of the goalkeeper and Aberdeen still lead.

Joel Nouble is producing all the flicks and tricks, finding Jason Holt in the box twice in quick succession - but nothing comes of it.

Livingston certainly looking the more likely to score the next goal.

A great chance for St Johnstone. A corner comes in and Andy Considine hooks it towards goal, Ross Laidlaw saves, and then just about stops Nicky Clark dispatching the rebound.

Inverness are now level with Dundee through Cameron Harper.

Dale Hilson has given Arbroath the lead away to Morton and Steven Lawless has put Partick Thistle in front against visitors Cove Rangers.

Dundee United's Glenn Middleton takes the ball beyond Borna Barisic at the edge of the box as he runs on to an Ian Harkes pass, but his low shot is blocked by Allan McGregor's outstretched foot.

No goals but a very lively game so far in Perth. The woodwork will need a bandage after getting a couple of clatters from the ball so far.

County are perhaps looking just a little bit more menacing going forward, with Akio and Olaigbe both really looking in the mood.

Ryan Jack robs Ian Harkes at halfway and strides forward before rolling in a pass for Scott Arfield. The Rangers midfielder steadies himself at the edge of the box and cracks a shot into the side-netting.

Aberdeen's Luis Lopes and Rangers' Antonio Colak have scored the only Scottish Premiership goals so far.

Kazeem Olaigbe has been bright for County so far. The left winger surged into the box, leaving Stevie May trailing in his wake, but scuffs his shot wide.
