Williams faces possible ban after red card

Liam Williams could miss Wales' opening game of the Six Nations after he was sent-off in Scarlets' Pro14 derby against Cardiff Blues.

Williams was shown a straight red for his dangerous entry into the ruck.

The 29-year-old, making his comeback following injury, made no attempt to wrap his arms and his head made direct contact with Shane Lewis-Hughes.

Wales face Ireland in their opening game of the Six Nations on 7 February.

Full-time - Cardiff Blues 29-20 Scarlets

After a poor performance against Ospreys on New Year's Day this was the perfect redemption for the Cardiff Blues.

Interim coach Dai Young will have been watching on with a smile on his face as the Blues scored three tries on their way to victory this evening.

Centres Willis Halaholo and Rey Lee-Lo scored first-half tries before Tomos Williams put the Blues in control late in the game.

The Scarlets played the majority of the game with 14 men after Liam Williams' red card late in the first half for a dangerous clear out at the breakdown.

The Llanelli side did score tries of their own, through Jonathan Davies and Sione Kalamafoni but it wasn't enough on the night.

What a day of rugby it has been!

Penalty - Cardiff Blues 29-20 Scarlets

And put them two scores ahead he does!

Time is not on the Scarlets' side as they restart the game with under two minutes remaining in Cardiff.

Huge penalty for the Cardiff Blues, Craig Evans says the Scarlets defenders entered the breakdown from the side.

Jarrod Evans will look to put the Blues two scores ahead.

Rhys Carre is back on the field as the Cardiff Blues return to 15 men.

The way this game has gone that should spell a chance for the Scarlets.

Penalty - Cardiff Blues 26-20 Scarlets

The Blues extend their lead through the boot of Jarrod Evans, who has been excellent this evening.

Six minutes remain at the Cardiff City Stadium.

What a chance that was for Steff Evans, the Scarlets wing kicks the ball down field and is completely clear.

But Evans couldn't make contact with the ball with his kick at the second time of asking and instead the Scarlets concede a penalty.

Let off for the Blues.

Both teams seems to be better when they're a man short.

Scarlets scored a penalty with Gareth Davies in the sin bin during the first half then conceded as soon as he returned.

Then the visitors started the second half on top despite Liam Williams' red card and now with Rhys Carre in the sin bin the Blues score their third try.

Strange game.

Try - Cardiff Blues 23-20 Scarlets

Jarrod Evans is at the centre of things again for the Blues, his cross field kick is well collected by James Botham before he side stepped Jonathan Davies.

Tomos Williams is quick to the breakdown and sneaks down the blind-side to restore the Blues' lead.

Evans' conversion shaves the outside of the post so it remains 23-20.

Replacements

Some replacements to catch you up on quickly.

Ben Thomas is on at centre for the Blues in place of try-scorer Willis Halaholo.

And the Scarlets have a new half-back pairing, Kieran Hardy and Sam Costelow are on in place of Dan Jones and Gareth Davies.

Sin-bin - Rhys Carre

What a turnaround in this second half so far, and now the Blues find themselves down to 14 men as Rhys Carre is shown a yellow card for an off-the-ball no-arms challenge.

No stopping him from there!

It wasn't caught by the live TV cameras, but Shane Lewis-Hughes harboured no hard feelings towards Wales colleague Liam Williams for his red card challenge.

Converted try - Cardiff Blues 18-20 Scarlets

This is all about the strength of Sione Kalamafoni.

The Tongan number eight picks the ball up from the back of the scrum and bulldozes his way through two Blues defenders to cross for the try.

Leigh Halfpenny adds the extras and the 14 men are ahead.

The 14 men are continuing to press here and they have a scrum five metres out.

Cardiff Blues' defence is holding firm at the moment though.

From one end to the other, the Scarlets now have a line out of their own five metres from the Blues try line.

Once again though the Scarlets defence stands firm, Josh Macleod smothering the ball at the breakdown to win the penalty and relieve the pressure.

Josh Adams wins the Blues a penalty at the breakdown and Jarrod Evans kicks the ball deep into the Scarlets' 22.

Dangerous moments for the visitors here.

The Blues are seemingly rushing into attacks at the cost of ball security, Scarlets have turned the ball over twice in as many minutes as they continue to press.
