**With Munster and Scarlets both in contention to finish the regular season at Conference B’s summit, this Guinness PRO14 meeting at Thomond Park has the ingredients to be a cracker.**\n\nThe top three are separated by just six points with Edinburgh leading the way, three points ahead of Munster.\n\nBut wins for Edinburgh and Munster this weekend would see the two sides start to break away from the rest as the season heads into its final eight rounds.\n\nShould Edinburgh lose to Cardiff Blues, a victory for the Limerick club could even see them return to pole position.\n\nBut Scarlets will be determined to stop Munster from claiming a third win on the spin as they look to strengthen their own bid for top spot.\n\nAfter losing to Edinburgh, Scarlets got their campaign back on track with a 36-17 success over Isuzu Southern Kings to stay on Munster’s coattails.\n\nThey have also been boosted by Steffan Hughes’ comeback from injury while Munster have made five changes to the team that beat Zebre last week.\n\nBilly Holland returns to captain to the side while Chris Farrell is back from international duty and Dan Goggin, Kevin O’Byrne and Stephen Archer have also been recalled. \n\n**Kick-off:** 5pm\n\n**How to watch:** Live on Premier Sports 1, eir Sport 1, DAZN, pro14.tv\n\n**Players to look out for:** Jack O’Sullivan v Uzair Cassiem\n\nIt will be youth versus experience at No.8 as rising star O’Sullivan comes up against the dangerous Cassiem.\n\nIt has been a breakthrough season for O’Sullivan who made his Guinness PRO14 debut against Dragons in September 2019 and secured a three-year senior contract last month.\n\nThe 21-year-old academy player keeps his place in the starting line-up as he prepares to make only his seventh first-team appearance.\n\nAnd considering the magnitude of the match and the opposition this is set to be one of O’Sullivan’s sternest tests in his fledgling career.\n\nCassiem is eight years older than O’Sullivan and will look to use all his back-row nous to get the better of his opposite number.\n\nNo player has made more carries than Cassiem in the league this season with 138 in just 10 matches as he constantly gets Scarlets over the gain-line.\n\nThe eight-cap Springbok also scored his first try of the campaign in Scarlets’ victory over Kings last weekend.\n\n**Key stat:** Munster’s lineout success rate of 91 per cent is the best across the two conferences while Scarlets have the worst after Round 12 with 83 per cent. \n\n**Munster:** Mike Haley, Calvin Nash, Chris Farrell, Dan Goggin, Darren Sweetnam, JJ Hanrahan, Craig Casey, James Cronin, Kevin O’Byrne, Stephen Archer; Fineen Wycherley, Billy Holland (CAPT), Arno Botha, Chris Cloete, Jack O’Sullivan.\n\n**Replacements:** Diarmuid Barron, Jeremy Loughman, John Ryan, Gavin Coombes, John Hodnett, Nick McCarthy, Rory Scannell, Tommy O’Donnell.\n\n**Scarlets:** Angus O’Brien, Corey Baldwin, Paul Asquith, Steff Hughes (CAPT), Steff Evans, Dan Jones, Jonathan Evans; Phil Price, Taylor Davies, Werner Kruger (CAPT), Lewis Rawlins, Sam Lousi, Aaron Shingler, Josh Macleod, Uzair Cassiem. \n\n**Replacements:** Ifan Phillips, Dylan Evans, Javan Sebastian, Tevita Ratuva, Steve Cummins, Dan Davis, Dane Blacker, Ryan Conbeer.
