Aberdeen v Ross County (Sun, 15:00)

Striker Marley Watkins, who has returned to Aberdeen from Cardiff City after last season's injury disrupted loan spell, and on-loan Newcastle United midfielder Matty Longstaff could make their debuts.

Forward Connor McLennan is hopeful of returning following a hamstring strain, but midfielder Ryan Hedges and centre-half Andrew Considine remain sidelined.

Centre-back Jack Baldwin could make his debut for Ross County, having signed following his departure from Bristol Rovers.

Two loan signings, Coventry City midfielder Jack Burroughs and Southampton full-back Jake Vokins miss out again and are likely to be sidelined for several weeks yet.

Ross County manager Malky Mackay: "I jokingly said last weekend 'thanks Neil!' to [SPFL chief executive] Neil Doncaster because of the fixture list we've been given.

"It is what it is. We knew we'd be playing the top teams in the opening weeks of the season, but you get on with it. It's a new-look Aberdeen, with a new manager, new assistant manager, fresh faces in the team, fairly new owner, so a slightly different Aberdeen we'll be facing."

Did you know? Aberdeen have gone four games without a win, with Thursday's defeat by Qarabag ending a run of three consecutive home wins, while County have not won in three outings.

St Mirren v St Johnstone (Sun, 15:00)

St Mirren manager Jim Goodwin will be back in the technical area having sat out the 6-0 defeat by Celtic after testing positive for Covid-19.

However, midfielder Alan Power is suspended after being sent off at Celtic Park.

St Johnstone defender Liam Gordon will again be assessed having just failed to prove his fitness ahead of Thursday's Europa Conference League play-off defeat at home to LASK.

Midfielder Craig Bryson is likely to miss out again, while Finnish striker Eetu Vertainen is unlikely to be eligible until after the international break.

St Mirren assistant manager Lee Sharp: "Jim is fine. I have spoken to him quite a few times this week and he is all good and looking forward to getting back in tomorrow [Saturday].

"Jim spoke to a lot of the boys individually. It was a case of, 'it's done now, let's move on and focus on the next game'. Everybody was upbeat when they returned on Tuesday, the mood was very good and training has been excellent this week."

St Johnstone manager Callum Davidson: "We have competed against two top teams in Europe, didn't let themselves down and we nearly got through to the group stage of the Conference League.

"It has given them a taste of European football and I said to them let's make sure we get that again. We will refocus straight away and we will move on."

Did you know? St Johnstone have yet to win inside 90 minutes in any of their eight games this season, their only victory coming on penalties in a League Cup win over Championship side Arbroath, while St Mirren are without a win in four.
