Here we go....Stay with us for news of 11 more cup ties and those games in the Championship and League 2.

Are we in for any more shocks to follow Caley Thistle's win away to Ross County last night and Brora's defeat of Hearts in the previous round?

Formartine United manager Paul Lawson tells BBC Scotland: "Let's go and show what we can do and let Motherwell know they are in for a game.

"We've been in football long enough to know anything can happen. A lot of things need to fall into place, we need to have everyone at the top of their game and hope Motherwell have a few off theirs.

"I want the players to enjoy it, but you enjoy football when you play well and you work hard. Hopefully we can do that."

Forward David Hopkirk and midfielder Jack Hodge come into the Stenhousemuir line-up for defenders Adam Corbett and Jack Brydon.

For Kilmarnock, defender Ross Millen replaces Aaron McGowan, who is on the bench.

Fraserburgh: Leask, Cairns, Hay, Cowie, Simpson, Campbell, Beagrie, West, Harris, Young, Barbour.

Substitutes: Combe, Campbell, Davidson, Sargant, Butcher, Grant, Duncan, Henry, Finn.

Montrose: Lennox, C Ballantyne, Steeves, Mochrie, Waddell, Dillon, Webster, Masson, McLean, Milne, Watson.

Substitutes: Quinn, Callaghan, CF Ballantyne, Rennie, Johnston, Hawke, Campbell, Allan, Fleming.

After a well-earned break over the international period, Livingston boss David Martindale has the luxury of naming an unchanged starting 11 for their Scottish Cup tie with Raith Rovers.

Raith Rovers have played three times since Livi's last game, but John McGlynn's side have made the most of those outings by taking all nine points on offer, including a crushing 5-1 victory over local rivals Dunfermline earlier this week.

McGlynn makes one change to that winning side, with Ross Matthews replaced by Dylan Tait in midfield.

Aberdeen captain Joe Lewis tells BBC Scotland: "We've had 83% possession, 26 shots, their goalkeeper has made some big saves. It was a difficult afternoon but really pleased to be in the next round.

"I had a couple of saves, one of real note, but I thought in general we played some really good stuff.

"They're tricky side, we've played them before and they've been tricky games. That final piece of the puzzle finally came, just the once, but we could have had three or four."

Can St Johnstone make it a cup double this season?

The Perth side already have the League Cup in the McDiarmid Park trophy room.

Today, manager Callum Davidson sticks with his favoured 5-3-2, making just one change from their 1-0 win over Ross County on 20 March, with Stevie May taking over from Chris Kane up front.

Jason Cummings was on target in Dundee's 3-2 win over Dunfermline last time, but the striker must do with a place on the bench this afternoon.

Captain Charlie Adam, Cameron Kerr, Shaun Byrne and Danny Mullen all come in from the Championship hosts.

Hamilton and St Mirren make a couple of changes from their 1-1 Premiership draw before the international break, a result that deprived today's visitors of a top-six place in a dramatic finish.

Defender Ben Stirling and forward Callum Smith drop to the Accies bench, with Ronan Hughes and David Moyo restored to the starting line-up.

Skipper Brian Easton, 33, makes his 400th career appearance as he bids to lead Accies into the fourth round.

Meanwhile, St Mirren midfielder Ethan Erhahon and winger Dylan Connolly are preferred to Richard Tait and Kyle McAllister, who are both among the substitutes.
