Hearts could have been further ahead, but Dundee - despite offering little threat in attack - might have been level just before the interval when Hearts goalkeeper Jack Hamilton tipped Tom Hateley's free-kick onto a post.

St Johnstone lead thanks to Steven MacLean's close-range finish and it might have been two just before half-time when Graham Cummins slid in at the back post and somehow missed the target.

Inverness don't deserve to be behind. They have created chances but haven't tested Alan Mannus as much as they would have liked. 

Results as things stand mean Richie Foran's side will be adrift at the bottom. They can't afford to be at this stage.

A great start to the first half for Accies, with Massimo Donati firing them ahead. Not such a great finish, with Giannis Skondras sent off for a cynical hack.

Moments before half time, Hamilton's Giannis Skondras is sent off for a brutal late lunge on Ryan Dow, who was haring forward but only 10 yards or so into the opposition half.

Stuart Armstrong has an effort blocked by Scott Boyd as he looks to double his and Celtic's tally for the day. 

The home side have enjoyed near total dominance against Killie and the only downside for Brendan Rodgers is that the champions only have one goal to show for their first-half effort.

What a spectacular miss from Graham Cummins! Liam Craig curls in a cracking corner from the right, it bounces right on the goalline, and Cummins somehow scoops it high over the crossbar. That should've been 2-0, right on half-time.

Partick Thistle good value for their lead at the break. Kris Doolan's early goal was the first of a series of openings Motherwell struggled to deal with in the Firhill sunshine.

With Kilmarnock losing at Celtic Park, Thistle are on course to secure a top-six place with points to spare.

Well, immediately after that Saints opener, Caley sweep downfield, and Larnell Cole fires straight at Alan Mannus. For the second time in quick succession, the striker ought to have done better.

After a long delay due to protests from the home side, Rory Loy fails to beat Alan Martin from the spot.

Don Cowie's cross finds Arnaud Djoum six yards out, and he plants his downward header to the left of Scott Bain, but the Dundee goalkeeper produces a superb save to deny Hearts a second goal. 

Another chance for Inverness, as Larnell Cole drags his low shot a foot or so past the post from the edge of the Saints box. The basement boys are knocking at the door...

Celtic almost double their lead through Kieran Tierney. It's Mikael Lustig with the cross into the box but Tierney's effort with the outside of the boot goes past the post. The champions seem in the mood today.

Thistle scorer Kris Doolan is in on goal again after an incisive pass by Ryan Edwards but contrives to fire wide from the right-hand side of the six-yard box.
