We will be concentrating on the Welsh derby in Llanelli but there is also a URC finale for the Ospreys at Leinster.

The Welsh side attempt to throw a spanner in the works for the Irish province, who can climb above Stormers into second place in the table.

Ospreys bid farewell to Wales captain Jac Morgan and full-back Jack Walsh, and also aim to finish with a spirited performance after showing unity amid off-field uncertainty in 2025-26.

"We have an opportunity to finish with more wins and more points than we did last year," said head coach Mark Jones.

"That for us will be progress, particularly with everything that's gone on off the field."

We will give you all the score updates from Aviva Stadium.

A touch of bias here but thankfully this evening will not be the end of the rugby season in Wales.

Cardiff ensured that there will be Welsh representation in the play-offs when they stunned Stormers at the Arms Park last night.

It was a pleasure to be there for a terrific win in a raucous atmosphere, an event that my colleague Gareth Griffiths has summed up nicely in this story.

Cardiff are waiting to learn their quarter-final opponents - and it could be another encounter with Stormers in Cape Town - while Connacht also made it through by beating Edinburgh.

Ulster are left needing help after slipping to a defeat by table-topping Glasgow in Belfast.

Munster host Lions tonight and are currently a point behind their Irish rivals - the home side will need at least two bonuses in round 18 to make the play-offs.

Dragons were impressive when brushing a shambolic Scarlets team aside 28-5 in Newport on New Year's Day.

Tries by fly-half Tinus de Beer, hooker Oli Burrows, wing David Richards and replacement hooker George Roberts earned a bonus-point victory, with Scarlets' only score coming from wing Ellis Mee.

It set a new record for winning margin by Dragons in the fixture, and it was the third success of a five-match unbeaten run at Rodney Parade.

It is going to be a wet Welsh derby in Llanelli.

The rain is coming down here at Parc y Scarlets and could be here for some time.

Aaron Wainwright will undoubtedly be a big miss for Dragons when he leaves.

Someone will need to step up into that role next season.

I didn't think anyone could come through and be anywhere close to Taulupe Faletau but he's done that as a local boy. I'm thankful for the effort he's put in over the last decade.

It's great to see that Gareth Davies is having another season. He's such a competitive player and he's still fit and hard-working.

His experience around the squad will be so important.

Dragons are in familiar territory at the basement of the URC, with just Zebre beneath them, while they could finish as Wales' lowest-ranked side for an 18th time in 23 seasons.

However, this has undoubtedly been a dramatically improved season.

Dragons finished bottom of the URC for the first time in 2024-25, while head coach Filo Tiatia won just one game after taking over from Dai Flanagan - and that was in the Challenge Cup at Newcastle.

They have won seven times this season and that figure should have been higher after three draws.

Dragons failed to kick a drop-goal with the clock in the red against Sharks and missed winners from the tee versus Ospreys and Benetton.

Tiatia's side have proved a tougher nut to crack, as they showed when edged out by Montpellier in the Challenge Cup semi-final.

Famously travel sick, they have also won at Zebre twice and Stade Francais... can they record one more away win before clocking off?

Scarlets have improved greatly since Nigel Davies took the reins in January.

He arrived shortly after a nightmare performance in defeat by Dragons at Rodney Parade, with Dwayne Peel freed from off-field duties to concentrate on coaching.

Scarlets have been better, yet have still endured plenty of frustration.

They could easily have been going into this game after three wins on the spin but instead they imploded against Cardiff and conceded with the clock in the red, lost to Bulls after Handre Pollard's late kick, and Ospreys' Jac Morgan went over in the 75th minute to earn west Wales derby bragging rights last week.

Davies will be demanding an 80-minute effort to finish the season.

Dragons feature all five of their players from the Wales squad - tight-head prop Dillon Lewis, lock Ben Carter, blind-side flanker Ryan Woodman and number eight Wainwright start, with back-row forward Harri Keddie on the replacements bench.

Two players feature for the last time - Wainwright, in his 138th appearance for the club, and starting scrum-half Niall Armstrong.

An injury to loose-head prop Rodrigo Martinez means that former Scarlets favourite Wyn Jones starts.

Dragons: O'Brien (co-capt); Richards, Inisi, Owen, Dyer; De Beer, Armstrong; W Jones, Coughlan, D Lewis, S Davies, Carter (co-capt), Woodman, Young, Wainwright.

Replacements: Dee, R Jones, Coleman, Douglas, Keddie, R Williams, Ackerman, Anderson.

Scarlets say farewell to former Wales lock Jake Ball, who has retired, and Munster-bound South Africa hooker Marnus van der Merwe today.

Sadly neither are able to take to the field due to injury, and Nigel Davies is also without influential number eight Fletcher Anderson because of a groin injury suffered against Ospreys.

The lengthy injury list also includes three players selected in the Wales squad for the summer - centre Eddie James, wing Ellis Mee and fly-half Sam Costelow.

Six of Steve Tandy's national squad do feature in the home side - Ospreys-bound Tom Rogers (pictured above) and fellow wing Blair Murray, centre Joe Roberts, fly-half Joe Hawkins, hooker Ryan Elias and number eight Taine Plumtree.

Scarlets: I Jones; Rogers, Page, Roberts, Murray; Hawkins, Blacker; Morse, Elias, Holz, Price, Douglas, Taylor, Macleod (capt), Plumtree.

Replacements: H Thomas, Sam O'Connor, Harri O'Connor, Davis, O Williams, G Davies, Leggatt-Jones, J Davies.

There was the drama of the battle for the United Rugby Championship (URC) play-offs - and scrap for top spot - last night.

This evening we have a shoot-out to avoid the unwanted honour of being Wales' lowest-ranked side and claiming the Welsh 'wooden spoon'.

Scarlets and Dragons are currently locked on 25 points, with Nigel Davies' side having the edge on win count.

Neither can catch Benetton, while Zebre are the URC's bottom side.

Granted, 'the race for 14th' won't catch on but that is what is up for grabs in Llanelli.

Here are the line-ups...
