Cardiff v Scarlets Live: Kick-off time, TV channel and latest score updates as Gatland watches on

Cardiff face the Scarlets in what should be a humdinger of a Welsh derby at the Arms Park this evening (5.15pm kick-off).

Returning Wales head coach Warren Gatland, along with his forwards coach Jonathan Humphreys, will be in attendance to run the rule over potential options for his Six Nations squad, which will be named over the next week or so.

Cardiff will be desperate to come out on top with Dai Young's side just a point outside the United Rugby Championship play-off places. The Scarlets have endured a difficult season but did beat Dragons RFC on New Year's Day to claim just their second URC victory of the season. Both Liam Williams (Cardiff) and Leigh Halfpenny (Scarlets) will go head to head in an interesting Six Nations subplot.

Cardiff v Scarlets is being broadcast live on Premier Sports/Viaplay, and will be replayed in full on S4C at 9.45pm, after the channel's live coverage of Ospreys v Leinster at 7.30pm.
