Hearts would be ahead if it wasn't for a fine save from Zander Clark. Sam Nicholson flies down the wing on the break and his low cross is met by Faycal Rherras, but the goalkeeper does well to reach out a hand to paw away the full-back's low drive from 15 yards.

Josh Windass is catching the eye for Rangers as he sprints forward and takes the ball wide of the keeper but Ross County get defenders back in time to protect their goal...

Hearts are coming more into the game in Perth and Tony Watt's shot on the turn inside the penalty box following a corner is deflected wide on the line by the head of Richard Foster, who knew little of that and is left seeing stars.

"Accies are being ripped apart here. They just can't handle balls into the box."

Souleymane Coulibaly scored a memorable overhead kick last week and the Kilmarnock forward is at it again, this time drawing a save from Ryan Scully from around 15 yards.

Saints are dominating possession, but it is Hearts who have had the only attempt on goal, Sam Nicholson driving straight at goalkeeper Zander Clark after a fine run and through ball from Tony Watt on the break.

A vicious shot from Ryan Edwards flies into the side-netting of the Kilmarnock goal as Thistle make a positive start at Rugby Park.

Louis Moult heads into the far corner and neat build-up play from Motherwell, but the assistant's flag cuts short the celebrations.

Josh WIndass converts a James Tavernier cross but the Rangers midfielder is offside...

The home side have started at a blistering pace. Louis Moult is causing all sorts of problems on the right hand side, and his ball across for Scott McDonald picks out the Australian in the box, but he swipes his shot wide.

League Two promotion hopefuls Clyde grab the first goal of the day, with Sean Higgins on target.

And we're off!

Motherwell manager Mark McGhee: "Bragging rights for the local fans are important but more important are the three points. Hamilton Accies are never down and out in games they always keep going.

Hamilton manager Martin Canning: "The pitch looks the best I've seen it in years - that motivates you to play well. Mikey Devlin is back fully fit which is great for us. Alex D'Acol wasn't feeling 100% so Eamonn Brophy takes his place. This derby means a lot to everybody and we're up for it."

There has long been talk of the 'curse of the manager of the month award' but it seems like that might have spread to the player prizes as well since Liam Boyce is nowhere to be seen on the Ross County team-sheet. 

The striker has been in top form, with six goals this season, and I gave him a big build up earlier on...

The big team news for Motherwell is that striker Louis Moult starts today after a recovering from a groin injury that's hampered him since the end of last season. The Englishman came off the bench to score a penalty last week and Mark McGhee hopes he can last "at least an hour" today.

Hamilton Accies are glad to have captain Mikey Devlin back at the centre of defence after he missed the Hearts game last week through injury. Accies also give a start to Eamonn Brophy, their young striker who manager Martin Canning says has been "champing at the bit" in training this week.

Lee Clark fields the same Kilmarnock team for the first time this season for two successive games. Thistle counterpart Alan Archibald brings in Ryan Scully, Ryan Edwards and David Amoo for Tomas Cerny, Sean Welsh and Ade Azeez.

There could be a bit of needle at McDiarmid Park, with Hearts head coach Robbie Neilson again brushing off suggestions that his players are earning a reputation for diving.

Neilson is insisting his side get penalties and fouls because they are so attacking, but opposition boss Tommy Wright said it has influenced his team talk this week.

"We have worked on discipline in the final third," he told BBC Scotland. Reiterating comments made earlier in the week, he added that it was not just his opinion that "some teams" went down easier than others.

Asked if that might annoy today's opponents, the St Johnstone boss replied: "Plenty of people irk me in football."
