The Scarlets host Cardiff Blues this evening in a rearranged Guinness PRO14 derby.
Just weeks after Cardiff came out on top at Cardiff City Stadium, the two sides will face off each again in a derby that will also see a host of Wales' Six Nations stars return from injury.
The reason the sides meet again so soon is the return league fixture has been brought forward from the weekend of March 6 to fill the gap created by the suspension of European cup rugby.

What's the team news?
Josh Navidi and Ken Owens will both make welcome returns to action in Friday night’s rescheduled clash between the Scarlets and Cardiff Blues.
Back rower Navidi hasn’t played since August, having suffered concussion during an internal training match with the Blues in September.
And Lions hooker Owens has been sidelined since October, following shoulder surgery after being injured against Glasgow.
Both men have been named on the bench for the Guinness PRO14 encounter at Parc y Scarlets.
There’s further good news on the Six Nations front, with second row Jake Ball returning for the Scarlets following a lay-off with a knee problem.
Ball comes back in, along with fellow Wales squad members Wyn Jones and Ryan Elias, plus back three man Johnny McNicholl, who takes over from the suspended Liam Williams.
Another Six Nations selection, flanker Josh Macleod, sits the game out with an ankle niggle, while props Samson Lee and Rob Evans remain sidelined with concussion, along with Rhys Patchell.
For the Blues, Matthew Morgan makes his 100th appearance and interim director of rugby Dai Young takes charge of his first game since returning to the region.
They make two changes, both in the pack, with Seb Davies coming in at lock following his omission from the Wales squad and Alun Lawrence starting at No. 8 amid a back-row reshuffle with Shane Lewis-Hughes ruled out through injury.
Scarlets: Leigh Halfpenny; Johnny McNicholl, Jonathan Davies (capt), Johnny Williams, Steff Evans; Dan Jones, Gareth Davies; Wyn Jones, Ryan Elias, Javan Sebastian, Jake Ball, Sam Lousi, Blade Thomson, Ed Kennedy, Sione Kalamafoni.

What have the coaches said?
Scarlets coach Glenn Delaney said: "It is great to have Dai back in the game, I have known him a long time and he is a good rugby man, a Cardiff man through and through.
"We have caught up a couple of times and he is enjoying being back in the hot seat. They will be focusing on what they can bring to this contest and we are no different.
"We have learned a lot from the defeat and you can't stand still, as long as we are taking things from the game that apply. We have another chance and we are looking forward to it."
Blues boss Dai Young said: "Discipline has been the theme of the week for us. There are plenty of positives from the win a fortnight ago, but also plenty of learnings.
"On the whole it was a good performance, but there was a 20 minute spell where we conceded a series of penalties and allowed Scarlets back into the fight.
"We’re eager to show the same intent and innovation with ball in hand, and there are plenty of boys in that side who can cause problems for the opposition defence, but it all starts with our work up front.
"We’ve decided to keep faith with the boys that secured the victory last time out and they’ve all deserved another shot.
"We’re expecting a backlash and a reaction from a proud Scarlets side, who will be out to prove a point in their own back yard. It’s up to us to match that intensity.
"There will be a few boys in there who will be disappointed to miss out on international selection this week. The best thing they can do now is put their head down, react positively and prove a point in a big derby encounter."
