It's an early yellow card for Dundee Utd centre-half Lurie Iovu for a challenge on Dennis Geiger.

St Mirren are doing well to nick the ball off a sloppy Killie side, but like so often this season their final ball is letting them down in the opening exchanges.

Classic Simon Murray as the Dundee striker gives the Livingston defence no peace and they concede a corner.

Cameron Congreve's delivery is headed over by home centre-half Luke Graham.

Early chance for Dundee as Joe Westley gets in behind the Livingston defence to latch on to Yan Dhanda's pass and fashions a shot wide.

The striker did well to stay onside there, but the shot had neither the accuracy nor the power.

St Mirren look to stamp their authority early in this crunch match as midfielder Killian Phillips smashes into a tackle out wide.

A big away following felt that was a foul. Nope.

As kick-off approaches, the sprinklers get a final twirl on-field to dampen the surface a little.

The flags are flying in the home sections of the stadium, which are filling up to capacity.

The away end is a mass of blue and white, completely sold out.

While Premiership survival is not at stake this afternoon, both sets of supporters know that victory today could go a long way to securing it.

There's a cracking atmosphere building as we prepare to bring you full, live commentary on BBC Radio Scotland.

A unique final is in prospect given Clyde and Hamilton are leading their respective League 1 play-offs.

Clyde are currently based at The Hamilton Community Stadium after leaving Broadwood Stadium in Cumbernauld in 2022 following a dispute with North Lanarkshire Council.

Meanwhile, Accies have been playing at Broadwood, 15 miles from Hamilton, this season after a dispute between the club's former owners and the stadium owners.

Accies' new owners plan a return to New Douglas Park next season and, with Clyde still searching for a new permanent home in Glasgow, the play-off final could decide which of them will be hosting League 1 football there and which will be playing in League 2.

After a second successive league title, Brora are looking to reach the senior leagues for the first time in their history.

Having lost in the semi-finals to East Kilbride last season, they were spared another meeting with Lowland League champions when Linlithgow Rose were told they did not qualify for promotion because of their lack of facilities.

Steven Mackay's side have lost just once in nine outings but have now won just once in four, although that was a vital 2-1 defeat of eventual runners-up Brechin City.

It is Brora's first final since losing to Montrose in 2015, when they defeated Edinburgh 4-2 on penalties after two 1-1 draws in the semi-final.

Brora also won the only previous meeting, 3-2 in the capital in a Scottish Cup tie the previous year.

Kilmarnock manager Neil McCann tells BBC Scotland: "I'm not going to change my message. We encourage the players to take risks. Without risk, you don't get any reward and today is no different.

"We've been full of focus but relaxed at the same time. We're looking forward to the start of the game.

"We don't change in terms of instruction. Today is standing on its own merits. We know how big a game it is."

Edinburgh City's 10-year spell in the senior leagues is under threat after they finished bottom of League 2.

Although that was largely down to a 15-point deduction for financial problems, Michael McIndoe's side had suffered seven consecutive defeats before ending the league season on a high with a 5-0 thrashing of second-bottom Dumbarton.

Edinburgh head north to face Highland League champions Brora Rangers without a win in seven away games, all without scoring, and losing the latest six for the loss of 20 goals.

St Mirren interim boss Craig McLeish tells BBC Scotland: "Conor [McMenamin] gives us attacking threat in the wing-back role. The bit we're missing is cutting edge in final third and hopefully he brings us that.

"There hasn't been any [anxiety] that's crept into out performances. We just haven't been good enough in the final third all season.

"It's about putting points on the board now. It's a confident group, these are the games you want to be involved in.

"This is as big a moment as any."

Dundee United manager Jim Goodwin tells BBC Scotland: "I don't think any of us saw that performance at Rugby Park coming [3-0 defeat].

"We've both [Dundee United and Aberdeen] underachieved in the league, it's as simple as that. We had a great season, last season, finishing fourth. We wanted to replicate that and at worst finish in the top six.

"Without us making excuses, you've got to give credit to Motherwell and Falkirk. We'll hope to make some changes in the summer.

"I'm sure Stephen Robinson will do the same. Hopefully that will put us in a better position for next season's campaign."

The Spartans will have to overcome a two-goal deficit if they are to win promotion to League 1 for the first time.

Their title challenge having faltered in the final run-in, Douglas Samuel's Edinburgh side are now three games without a win, having won only twice in eight outings, and have also failed to win their latest three at home.

Clyde's only defeat in six outings came with a 5-0 thumping on their last trip on the road as East Kilbride clinched the title, manager Darren Young having rested some players in preparation for the meeting with the eventual runners-up.

The Bully Wee have never won in eight visits to Ainslie Park, losing 2-1 in March and drawing 1-1 in November, but a repeat of either would be enough to take them to the final as they look to end a three-year spell in League 2.

Hamilton Academical continue to be a club in turmoil off the park and face a winding up order from HMRC.

However, they expect that to be withdrawn by the tax authority once they pay a debt owed by the previous owners - and they also look strong favourites to reach the play-off final and retain their place in League 1.

Darian MacKinnon's side only find themselves in the play-off thanks to a 21-point deduction for off-field rule breaking and they entertain Forfar Athletic having lost just once in five outings, winning the other four.

Their 3-1 first-leg win at Station Park ended a six-game unbeaten run that had taken Jim Weir's Forfar to fourth in League 2 and was Accies' fourth win in a row over the Angus side.

Aberdeen manager Stephen Robinson is singing the praises of returning centre-back Mat Knoester.

"He's a key part of giving us stability, experience, and a voice," he tells BBC Scotland.

"We're up against a Dundee United side who rely a lot on balls into the box and long throws and we have to match that area.

"We want to continue the momentum we feel we've created so far in the last three games.

"We want to win every game between now and the end of the season and finish seventh, which would guarantee our safety at the same time."

Hibs head coach David Gray tells BBC Scotland: "The incentives are clear for both sides going into the game.

"I've spoken a lot about this, but in the post-split fixtures, everything's still achievable for everybody within it, so expect there to be twists and turns from there on.

"But this game's really, well, the biggest game of the season for us now.

"We know what's at stake. The players are ready for it."

Stenhousemuir have paid the price for their highest-ever league finish.

Challenging Inverness Caledonian Thistle for the League 1 title until the final day of the season led to manager Gary Naysmith being poached by Championship club Ayr United for next season.

However, the former Scotland full-back can still make more history before exiting.

Having finished fourth last season, Stenhousemuir lost in the play-off semi-final to Airdrieonians last season but will be confident of reaching their first final after a 1-1 draw away to Queen of the South in the midweek first leg.

Naysmith's part-time side have lost just once in 14 outings and the Dumfries side have not won on their latest four visits to Ochilview Park.

However, Peter Murphy's full-timers are themselves unbeaten in 10 outings, including five on the road, although only three of those were wins as they look to end a four-year absence from the Championship.

Indeed, they have drawn four of their five meetings with Stenhousemuir this season, although they lost 2-0 on their latest visit in January.
