Motherwell's Tawanda Maswanhise is wearing a protective mask today after a recent jaw injury.

Shout for a handball in the Hearts box now as Dundee United enjoy a surge in momentum.

Jesse Randall's cross was cut back nicely to Dylan Tait, but his shot was well blocked by Jamie McCart. No spot-kick given.

The United captain then cuts Sabah Kerjota in half with a tackle, but escapes without punishment.

Emmanuel Longelo breaks down the right for Motherwell and lays a lovely pass off to Tawanda Maswanhise inside the Falkirk box but a defender gets in front of the Well attacker and sends the ball behind for a corner.

Lukas Fadinger delivers but the visitors get it clear. A few passes later, Motherwell are back in as Ibrahim Said crashes a shot off the crossbar.

Hearts are enjoying the kind of start to their game that Celtic had at Rugby Park.

Will it be another goal-fest at Tynecastle?

Remarkable, really, how seamlessly Motherwell have moved into this season despite the loss of their manager and a number of their most influential players from that wonderful campaign last year.

Oscar Preiestman is having a ball out there, spraying balls about the place, while Tom Sparrow and Willy Vogt are looking dangerous.

They're such a good watch.

First booking of the match and it goes to Amadou Ba-Sy of Hearts.

The striker takes a big touch and then lunges in to try and retrieve the ball, but catches Bert Esselink on the shin with his studs.

It seems to be a glancing blow and it's only a yellow.

A comfortable win for champions Celtic with Kasper Hogh's first-half hat-trick added to by goals from Benjamin Nygren and Luke McCowan.

No points so far for Kilmarnock and nine goals conceded after two Scottish Premiership games.

Three minutes of added time being played at Rugby Park, about midway through that.

Celtic are in for a sixth with James Forrest latching on to Arne Engels' pass, taking a touch and blasting a shot across the face of goal.

Falkirk win a free-kick about 25 yards from the Motherwell goal and Ethan Ross steps up to take but the 24-year-old cannot keep his effort down and it sails over the crossbar.

Hibernian, like Rangers, were playing European football on Thursday and also make changes - four in total.

Kanayo Megwa takes over from Felix Passlack at right-back, Josh Campbell comes into midfield and Ante Suto and Thibaut Klidje form a new front two, with Owen Elding, Nathan Lowe and Passlack dropping to the bench and Martin Boyle not in the squad.

Already Motherwell are looking more dangerous.

Tawanda Maswanhise has just fired a shot wide of the post. Lukas Fadinger had been tackled inside the Falkirk box moments before and the hosts were appealing for a penalty but the referee was not biting.

Falkirk go up the other end and force a comfortable save from Alex Paulsen.

Kevin Clancy is over to the monitor. It looks like Daniel Bennie grabs hold of Jamie McCart and stops the Hearts defender from attempting to jump for the ball.

Looks a penalty, you have to say.

Shouts for a handball in the Dundee United box as Amadou Ba-Sy fizzes a cross in from the left. Did it strike Josh Rawlins?

Kevin Clancy has paused play... and quickly waved play on.

And then, from another corner, there's another big shout for a Hearts penalty. Was Jamie McCart being held?

Play is paused again.

Kasper Hogh is replaced by Callum Osmand for the closing stages after a hat-trick scoring performance for Celtic at Rugby Park.

Hearts have been buoyed by that goal and they're pouring forward down the right now.

Sabah Kerjota cuts it back for Claudio Braga and his shoot takes a deflected loop that drops just past the post.

Corner coming... but it's comes to nothing.

Olwethu Makhanya makes his Rangers debut and Vanja Dragojevic his first start for the club in two of six changes to Derek McInnes' starting line-up.

Cammy Devlin and Nico Raskin come in to midfield while Findlay Curtis and captain Lawrence Shankland join the attack.

It looks like a 3-5-2 formation from Rangers with Makhanya partnered in defence by Emmanuel Fernandez and Tuur Rommens.

Thelo Aasgaard, Tochi Chukwuani, Mohamed Diomande, Ross McCrorie, Dan Neil and Djuon Sterling all drop to the bench.

It's been a lively start at Fir Park but no goals to speak of yet.

Falkirk are passing the ball about nicely but Motherwell are pressing very aggressively.
