Nico Raskin tries an ambitious one but Dumbarton keeper Harry Broun watches it go off target.

Feels like a goal is coming for Rangers, but Philippe Clement will be desperate for his side to be more clinical.

Cyriel Dessers should be on a hat-trick already.

He gets away from his man in the box then hits narrowly over with his left foot.

A heavy Ross McCausland cross goes straight out and Dumbarton get a breather.

They've only had 22% of the ball, the home side.

Rangers should be three up.

Ross McCausland rolls one across goal and Rabbi Matondo blasts over from fewer than 10 yards.

First big chance of the evening and it's a big save from Harry Broun.

That'll do his confidence the world of good.

Big early chance for Cyriel Dessers, who is denied at close range by home keeper Harry Broun.

Todd Cantwell can't sort his feet out with the rebound.

Dumbarton need to stay in the tie as long as they can.

Stevie Farrell will have told them to make it compact and deal with any crosses that come their way.

From the early part of the game, it's evident that's how Dumbarton will play.

Todd Cantwell meets a cross on the penalty spot.

But he gets his volley all wrong and it's way off target.

Decent chance, that.

Today is a day for the Dumbarton players and staff to go and showcase themselves.

Nobody expects anything from them. Can they pull off a huge Scottish Cup shock?

As expected, early possession for Rangers.

But the hosts don't look too fazed and have managed the first couple of minutes well.

The ball is... bobbling.

Dumbarton manager Stevie Farrell tells BBC Scotland: "It's been a long week. The ground staff deserve all the credit, particularly the work they've done this morning.

"We actually expected them to play a strong side. We prepared for it. We're going to have to be at our very, very best.

"The important thing when you play a team like Rangers is that your intensity levels are as high as possible. We need to be brave and enjoy it."

Speaking to BBC Scotland, Rangers boss Clement has voiced some concerns about the Dumbarton pitch, which passed a pitch inspection earlier today.

He expects it to be tough to put more than two passes together.

Rangers manager Philippe Clement tells Viaplay: "The most important thing is to qualify. In every round, there are surprises across Europe with teams that are not focused enough.

"This not a field players are used to. It will be hard to play two passes without the ball bouncing high."

Robby McCrorie gets a rare outing between the sticks for Rangers, replacing Jack Butland.

Meanwhile, new loan signing Fabio Silva starts on the bench.

Neil Lennon's son, Gallagher, is among the Dumbarton substitutes. I'm sure he'll receive a warm reception from the travelling fans...
