Peterhead have come good and their 10-game unbeaten run, combined with East Fife's indifferent form, means they host fifth-top Spartans with a four-point lead at the top of the fourth tier.

Game of the day, though, is third-top Edinburgh City hosting the side one place and three points behind - Elgin City.

At the bottom, and because of their poor goal difference, Bonnyrigg Rose, who have gone 10 games without a win, will be all but be consigned to a Pyramid Play-off if they lose at home to East Fife and Forfar Athletic, who have moved off the bottom having lost just once in six outings, win away to Clyde.

• Bonnyrigg Rose v East Fife
• Clyde v Forfar Athletic
• Edinburgh City v Elgin City
• Peterhead v Spartans
• Stirling Albion v Stranraer

Arbroath, unbeaten in eight outings, will win the League 1 title if they beat third-top visitors Stenhousemuir, who have not won in five, in a match being broadcast live on the BBC Alba television channel.

Second-top Cove Rangers, who have not won in four, are away to Dumbarton, who are unbeaten in four despite already being relegated because of their points deduction for going into administration.

Kelty Hearts, without a win in six, visit Inverness Caledonian Thistle in their first game since Charlie Mulgrew resigned as manager.

Ayr United's late equaliser denied Falkirk the chance to secure the Championship title this weekend, but because of their far superior goal difference, the Bairns will be all but there if Livingston lose to Greenock Morton for the first time in 10 meetings since 2016.

Win, though, and David Martindale's side will reduce the gap to six points and move five clear of third-top Ayr with three games remaining.

Morton need a win to maintain any chance of taking fourth place from Partick Thistle, who host a Hamilton Academical side looking to build on a win over Dunfermline Athletic that moved them up to third bottom.

Raith Rovers are unbeaten in six and now only three behind Thistle as they entertain an Airdrieonians side who are staging their own revival.

Queen's Park have been dragged into relegation battle after eight straight defeats, five at home, and having not scored in three outings as they host second bottom Dunfermline.

The Pars have won once in five as they have failed to respond so far to Neil Lennon's managerial appointment and they head to Glasgow having failed to beat their hosts in their latest six meetings.

• Greenock Morton v Livingston
• Partick Thistle v Hamilton Academical
• Queen's Park v Dunfermline Athletic
• Raith Rovers v Airdrieonians

St Johnstone manager Simo Valakari tells BBC Scotland: "We need to follow up [last weekend], otherwise it was just a nice weekend.

"We needed that result, we needed those points. We set the target to be somewhere when the split ends, we need to achieve something in this game, nothing has changed.

"We need to get some kind of run going and there's not better place to do it than today."

Hearts head coach Neil Critchley explains his decision to start Musa Drammeh ahead of Lawrence Shankland with James Wilson suspended.

"Musa did really well in training this week," he tells BBC Scotland.

"We want, in that position, pace and power and the ability to run in behind, which he brings. I wouldn't say Musa and Shanks are competing for the same position - Shanks has actually been playing in a different position.

"We always want to be competing at the top end of the league, so we know the importance of today. We want to bounce back from last week and this is our next opportunity to do that."

Just the one change for Simo Valakari's Saints from their big win over league leaders Celtic last weekend.

Drey Wright is out with an ankle strain, so experienced left-back Barry Douglas comes in to start.

Jim Goodwin makes two changes from United's 1-0 win over Hearts last weekend.

Midfielder Allan Campbell and striker Louis Moult make way for wingers Kristijan Trapanovski and Glen Middleton.

Just the one change for Neil Critchley's Hearts from their narrow defeat by Dundee United.

Motherwell have made two changes from their 2-0 defeat by Kilmarnock last time out.

Winger Tawanda Maswanhise is handed a start, while Tony Watt comes in to lead the line.

Kai Andrews and fellow forward Luke Armstrong make way, while here is also a place for defender Ewan Wilson on the bench.

County manager Don Cowie has made three changes to his starting XI, with the Staggies having lost 1-0 at home to Aberdeen last weekend.

Zac Ashworth comes in at left wing-back, Josh Nisbet joins the midfield and Ronan Hale is restored to the attack.

Jonathan Tomkinson, Kieran Phillips and Jack Grieves drop to the bench.
