Scottish League 1 champions Falkirk are in front at home to Kelty Hearts with Calvin Miller on target and League 2 strugglers Clyde are also ahead, Robbie Leitch on target at home to champions Stenhousemuir.

Also in League 2, Ross Draper has given Elgin City the lead against visitors Peterhead.

Glenn Middleton already looking lively for the hosts.

He's causing havoc down the left-hand side, creeping to the byline before seeing his effort deflected into the side netting.

A relatively quiet start to proceedings in the Scottish Championship, given what's at stake.

Partick Thistle's Kerr McInroy has threatened against Airdrieonians and Michael Garrity's effort for Morton at Arbroath was close but no goals so far.

That was some noise as the Dundee United fans strolled out on to the Tannadice turf.

A sea of tangerine as Jim Goodwin's side look to effectively wrap up a return to the top flight at the first time of asking.

It's time to get today's games under way.

Dundee United manager Jim Goodwin says he's told his players they can win the league today, despite the slimmest of arithmetic chances keeping Raith Rovers in it.

"The hardest thing in football is to get over the line," he tells BBC Scotland. "Raith had a very good result last night [by beating Inverness].

"I said to players you'd rather go and win it - we have a chance to win the league today. I know it's not mathematically done, but the goal difference, I can't see [Raith making it up] being likely.

"We've never been thinking too far ahead of ourselves. The players are in a really good place just now.

"Hopefully, we can go and get it done in front of a really good home support."

Stenhousemuir have won Scottish League 2 and Peterhead and Dumbarton will be in the promotion play-offs.

Spartans can join the Blue Toon and the Sons by beating Bonnyrigg Rose today.

All teams from Elgin City in sixth downwards are not yet safe from finishing bottom and entering the SPFL play-off final against either the Highland or Lowland League champions.

East Kilbride have won the Lowland League and one of Buckie Thistle, Brechin City and Fraserburgh will be confirmed as Highland League champions in today's no doubt thrilling last full day of fixtures.

They know what today means.

Falkirk are Scottish League 1 champions and Hamilton Academical are in the promotion play-offs. Edinburgh City will be relegated to League 2.

All that remains to be decided are the final two promotion play-off spots and the relegation play-off place.

Alloa Athletic can secure a promotion play-off place by beating Cove Rangers in the evening kick-off. Watch that game on BBC Alba, iPlayer and on the BBC Sport website and app.

One of Kelty Hearts, Queen of the South, Annan Athletic and Stirling Albion will be in the relegation play-off place but Kelty are all but safe - and not out of the running for the promotion play-off places.

Arbroath: Boruc, Walker, Steele, Teale, Delaney, Stewart, Gold, Mackinnon, Dow, McKenna, McIntosh.

Substitutes: Gaston, Slater, Jacobs, Stowe, Norey, Robinson, Murray, Lyon, Bird.

Substitutes: O'Connor, Quitongo, McGrattan, Bearne, Power, Murdoch.

Queen's Park: Ferrie, Tizzard, Fox, Longridge, Scott, Thomson, McKinstry, Welsh, Mauchin, Thomas, Paton.

Substitutes: Wills, Robson, Bannon, Sheridan, Bruce, Williamson, Turner, McLeish, Carse.

With Arbroath already relegated and second-bottom Inverness Caledonian Thistle having lost last night, the only thing that can change in terms of positions at the foot of the Championship today is Queen's Park climbing above Inverness up to eighth - if they beat Dunfermline Athletic at East End Park.

Of course, there would still be two games to play.

Partick Thistle play Airdrieonians in Glasgow's west end and both teams are bidding to sew up the last two play-off places in the Scottish Championship, with second-placed Raith Rovers already assured at least a play-off place.

Should there be a winner at Firhill this afternoon, that team will be guaranteed a play-off berth. The loser can still be assured a play-off spot if both Dunfermline Athletic and Ayr United fail to win. A draw and both Thistle and Airdrie are in the play-offs.

This is why Dundee United cannot absolutely seal the title and promotion today - Raith Rovers narrowly edging Inverness Caledonian Thistle last night.

On the drive up the M90 this afternoon, there was a van with a tangerine scarf lodged between each of the front windows.

It seems some are already in party mode, despite the fact Dundee United cannot officially be crowned champions today.

There's a job to do first, and Scott Brown's Ayr United arrive in the mood to spoil the celebrations.
