UFC 315 - Belal Muhammad vs Jack Della Maddalena LIVE: Start time, undercard, scorecards and round-by-round updates as Australian aims to spring title upset

The No 5-ranked flyweight looks like she's about to take Grasso's No 1 spot on after a very professional and largely risk free display. Her opponent, with blood on her face, made a fist of it but the judges all score every round for the Brazilian.

The Mexican knows what kind of battle she has to make this to win and its a dirty boxing type of ugly fight. Grasso was sick of being picked apart from range so forced her way in at the end of the second to blitz and bully, absorbing some punishment but also landing well.

The Brazilian has the better of round one and looks so quick, definitely possessing the speed advantage, landing a side kick to the face. The kicking has been excellent and aside from a couple of nice double jabs, Grasso has not quite got a grip of the fight yet.

Silva has won 12 in a row and has so much confidence coming into this one against the former champion.

We'll find out whether the Brazilian is truly elite UFC level tonight and she's a strong betting favourite for this flyweight contest tonight.

Sensational performance by Saint-Denis. He lands some brutal elbows and knee in the clinch, completely swarming the helpless Prepolec before securing an arm triangle to force the tap. There was a fair bit of anger in that display from BSD and his fight with Joel Alvarez will probably be remade now.

Prepolec survives, just. He hears the bell with BSD locking in a standing rear naked choke incredibly tight. The Frenchman secured an early takedown and then dominated the exchanges on the ground, albeit with his opponent defending the submissions deftly.

Benoit Saint-Denis' back-to-back defeats by Dustin Poirier and Renato Moicano have put his back against the wall and even though the French speaking district he's performing in might usually support him, he's facing a Canadian tonight in Kyle Prepolec. This should be a great lightweight contest.

Malott is the big winner so far tonight and will have bagged a few new fans for himself - who will rival him for a performance of the night bonus?

Those pre-lims really delivered and the Malott moment to top it off really has the crowd ticking ahead of the main card - with four fights ahead of the main event and two title showdowns.

He loaded up on that hook and stepped off the centre line to do the damage. A real career highlight for the Ontario man.

Huge moment for the Canadian on home turf as he connects with a clean left hook to floor Radtke and then land some brutal finishing shots on the floor, knocking out the gumshield and his opponent. Radtke needs help to a stool and Malott sits on top of the cage with the flag draped on his shoulders. He gets emotional in the cage afterwards - 'When it comes to defending this country in the octagon, know one thing Canada, I stand on guard for thee', he says.

In the featured pre-lim, home favourite Mike Malott's backing in taking the shape of a very, very loud chant against his opponent Charles Radtke.

To do this to Jessica Andrade, a legend of the sport, is one hell of a way to get the home crowd going. Brilliant from the flyweight, who is closing in on a title shot.

As soon as you say the words Montreal and UFC, there's only one man who springs to mind... Georges St Pierre, for many the GOAT of MMA. He's here with Aimann Zahabi tonight.

Lithuanian-British fighter Modestas Bukauskas 'The Baltic Gladiator' just took home a unanimous decision win on what Daniel Cormier thought was a dubious call. One just gave him every round and another said Cutelaba won all three, with the third scoring it to Bukauskas by a round. Weird cards.

The Kiwi almost finished a teak tough Ivan Erslan in the third round but had to settle for a unanimous decision in the end. He dropped him with a heavy right hand in the third and leapt on top but just could not find the fight-ending blow. Still, he moves to 7-0 with a really impressive showing.

What a lovely graphic this is from TNT Sport and outside of the main event, Jose Aldo will be a massive attraction. The CV isn't bad, is it?

The pre-lims have just started but we've already had the first bouts of the evening in front of the keen fans who found their seats early before the televised action at Bell Centre.
