Callum Slattery
Motherwell buy themselves a lifeline!
A fairly rubbish cross from the right hits Bevis Mugabi and drops perfectly out to Callum Slattery, who absolutely rifles it into the bottom corner from 20 yards. Game on!
Dundee United 2-2 Dundee
Dylan Levitt goes close to pulling the home side back in front as the midfielder's strike from the edge of the box whistles past the post.
Moments later, Nicky Clark's cutback finds Mark McNulty and his fellow striker skies it over from the penalty spot.
Matt O'Riley
The half-time substitute is having some fun.
A lovely touch and finish into the top corner from the Celtic midfielder.
FYI, I jumped the gun earlier - Kyogo Furuhashi is NOW on, along with James McCarthy.

Andy Halliday will not secure an Edinburgh derby hat-trick as the 30-year-old Hearts midfielder hobbles off injured to a huge ovation from the home support.
Livingston 2-0 Motherwell
Big shout for a penalty as Livingston midfielder Nicky Devlin goes over in the box.
It was Joe Efford who challenged him, with Devlin going down in stages, but referee Don Robertson only gives a goal-kick.
Matt O'Riley
O'Riley makes up for his miss a few moments ago with a diving header for Celtic's fifth.
A great cross from David Turnbull to pick him out. Kyogo Furuhashi has just come on.

Matt O'Riley should make it 5-0 to Celtic.
A lovely move and the ball is cut back to the Denmark Under-21 midfielder, but his low shot goes past the post.

Charlie Adam
Game on indeed!
Charlie Adam picks up the ball 30-yards for goal and takes a few touches to get the ball out of his feet, with everyone in Tannadice knowing what he was about to attempt.
His left-footed venomous strike appears to wrong-foot Benjamin Siegrist with the amount of swerve it has on it and nearly bursts the net.

Game on at Tannadice.
Cammy Kerr dinks in a cross that Benjamin Siegrist flaps at allowing Danny Mullen to score into a vacant net at the back post.
Not the best derby for goalkeepers so far...

And it could be three!
Odin Bailey in acres of space on the right, he cuts it onto his left and squares to Alan Forrest, who drags his first time shot wide. Livingston almost had the game out of sight.
Alan Forrest
After all that pressure, Livingston hit back and double their lead! Odin Bailey has a shot blocked, Nicky Devlin plays to Alan Forrest who has time to fluff his first shot, gather, and drill it into the bottom corner.

Liel Abada smashes a volley inches past the post for Celtic. It's relentless from the league leaders.
David Turnbull has replaced the outstanding Reo Hatate.
Livingston 1-0 Motherwell
Kevin van Veen is desperately unlucky not to find the equaliser!
Connor Shields whips a cross in from the right, Ayo Obileye hooks a clearance straight to Van Veen and the Motherwell striker hits the woodwork from close range.
It bounces off the back off Max Stryjek and trickles towards the back of the net, but the Livingston goalkeeper stops it on the line! So close to an equaliser.
Andy Halliday
It's a second for Andy Halliday and more great play from Barrie McKay.
McKay plays a delightful back heel to Halliday, who drives forward and cracks a low shot past Hibs goalkeeper Matt Macey.
Hibs' top-six chances are crumbling.

Absolutely sensational from Charlie Mulgrew!
United have a free-kick roughly five yards outside the side of the box.
The former Scotland defender stands over it with his left foot and everyone knows it's heading towards the back post, but no one can do anything to prevent it from whipping into the top corner. Magnificent!
