Leinster's Jordan Larmour forced off with an injury, replaced by Jimmy O'Brien.

Munster move the ball brilliantly through the hands and get to within five metres of the Leinster line, but get no further with the ball spilled forward.

Midway through the first half and it's been played at a lightning pace. Perhaps a little frantic at times, but hugely entertaining.

Injury issues for Leinster with Andrew Porter replacing Paddy McCarthy.

A good Munster move sparked by Jack Crowley dropping a deft kick into Thaakir Abrahams. Munster hammer the line but held up as we go back for a penalty.

Munster spread the play to the opposite flank but Edwin Edogbo can't gather and knocks on as Leinster get the scrum.

Alex Nankivell has replaced Andrew Smith on the Munster side as the winger appears to have picked up a hamstring injury.

A great kick through from Munster's Andrew Smith causes real problems with Jamison Gibson-Park forced to hack into touch. Munster now knocking at the door just metres away.

Leinster with all the early pressure and win another penalty, this time inside the Munster 22. Predergast goes for the corner...

We are under way at Croke Park with Munster kicking off. Leinster playing towards Hill 16 in the first half.

The teams are out onto the Croke Park pitch to a huge ovation from their supporters. Kick-off is just minutes away.

A massive result for Ulster - a real scalp for Richie Murphy’s side in Durban and three wins from three to start the campaign.

The Sharks never quite hit their stride and indiscipline told, while the men in white stayed composed throughout.

More action coming up as Leinster face Munster - stick with us for live updates.

Speaking on Premier Sports, man of the match Nathan Doak said of Ulster's victory against the Sharks:

“Sweet as they come. To come over here and win at a place like this is special - one I’ll remember for a long time. We’ll enjoy tonight, then it’s on to the Lions next week.”

On Ulster’s performance and togetherness:

“I love this team. I’m out there with my best mates and we’ll fight for everything. The South African lads like Werner and Juarno add massive value. Maybe I’ve even picked up a bit of Afrikaans - dankie!”

Games between Leinster and Munster are always special occasions, but this carries the added intrigue of the battle of Irish fly-halves.

Both Leinster's Sam Prendergast and Munster's Jack Crowley were included in Andy Farrell's 34-man squad for Ireland's upcoming autumn internationals.

This will be their last game before Ireland face New Zealand in Chicago on 1 November, so their respective performance may go a long way to decide who gets the number 10 jersey for the All Blacks clash.

Leinster have made two late changes to their starting team for their United Rugby Championship encounter with Irish interprovincial rivals Munster at Croke Park (15:15 BST).

Wing Tommy O'Brien and number eight Jack Conan - who were both named in Ireland's autumn squad earlier this week - were originally named in head coach Leo Cullen's starting line-up, but have failed fitness tests on back and knee injuries respectively.

Jordan Larmour comes in for O'Brien, with Max Deegan drafted in at number eight.

Jimmy O'Brien joins the replacements while Josh van der Flier assumes the role of captain in the absence of Conan after he also skippered the side in last week's 31-5 win over the Sharks.

Leinster: Jamie Osborne; Jordan Larmour, Garry Ringrose; Robbie Henshaw, James Lowe; Sam Prendergast, Jamison Gibson-Park; Paddy McCarthy, Ronan Kelleher, Tadhg Furlong; RG Snyman, James Ryan; Alex Soroka, Josh van der Flier (capt), Max Deegan.

Replacements: Dan Sheehan, Andrew Porter, Thomas Clarkson, Brian Deeny, Scott Penny, Fintan Gunne, Ciaran Frawley, Jimmy O'Brien.

Munster: Shane Daly; Andrew Smith, Tom Farrell, Dan Kelly, Thaakir Abrahams; Jack Crowley, Ethan Coughlan; Michael Milne, Diarmuid Barron, John Ryan; Edwin Edogbo, Fineen Wycherley; Tadhg Beirne (capt), Jack O'Donoghue, Brian Gleeson.

Replacements: Lee Barron, Jeremy Loughman, Ronan Foxe, Jean Kleyn, Gavin Coombes, Paddy Patterson, JJ Hanrahan, Alex Nankivell.

Ulster secure a massive win over a Springbok-laden Sharks at Kings Park in Durban.

First-half tries from Mike Lowry and Werner Kok, backed by Nathan Doak’s accuracy off the tee, set the platform with Siya Kolisi the hosts’ only scorer before the break.

After the interval Makazole Mapimpi and André Esterhuizen hit back, but further scores from Tom Stewart and Callum Reid sealed a statement victory for Richie Murphy’s men.

A great victory for Ulster in Durban but the URC action continues shortly.

We have live updates to come from Croke Park where Leinster host Munster.

Leo Cullen's side grabbed their first win of the new season last week against The Sharks and welcome a Munster side who have won three from three.

An exciting game in Dublin is in store.
