Meanwhile, stay with us for the team news as it comes in - and John Souttar's absence from Hearts' squad after Rangers failed to take the Scotland centre-half to Ibrox ahead of his pre-contract agreement in the summer is the big news so far...

The latest from Stark's Park is that controversial new signing David Goodwillie is not in the Raith Rovers squad as the fourth-placed hosts look to narrow the five-point gap with leaders Arbroath.

Visitors Queen of the South are three points adrift of Greenock Morton at the foot of the table.

Meanwhile, fifth-placed Partick Thistle host Ayr United, who are just a point ahead of Morton in the relegation zone.

With top two Rangers and Celtic facing up on Wednesday, focus at the top is third-placed Hearts' visit to neighbours Hibs, who are two spots behind.

Bottom three Ross County, Dundee and St Johnstone all face difficult games too.

Championship club Raith Rovers managed to knock Aaron Ramsey off the top of the news bulletins following their acquisition of David Goodwillie from Clyde.

Author Val McDermid has said she will withdraw her support and sponsorship from the Kirkcaldy club in protest at the arrival of the former Scotland striker who was ruled to be a rapist and ordered to pay damages in a civil case in 2017.

First Minister Nicola Sturgeon has also criticised the signing and two club directors have resigned.

Clyde faced a similar furore when they signed Goodwillie five years ago, but after the 32-year-old helped them avoid relegation from League 2, win promotion to League 1 and stay there, many of their fans were left disappointed by his decision to seek a return to full-time football.

Rovers said in a statement that they "respect the differing views among fans and stakeholders" but are sticking by their decision and Goodwillie is having a fitness test at Stark's Park ahead of a possible debut.
