Liam Williams will miss Wales' Six Nations opener against Ireland after he was given a three-match ban for his red card in the Scarlets’ defeat to Cardiff Blues.

The British and Irish Lions back was sent off for dangerously entering a ruck and making contact with the head of Blues flanker Shane Lewis-Hughes during last Saturday's Pro14 derby.

Following his dismissal, Williams said to referee Craig Evans: "Going to start playing touch, is it?"

Williams was banned for "three meaningful fixtures", ruling him out of the Scarlets’ trip to Leinster on 30 January and Wales’ Six Nations game with Ireland on 7 February.

The Pro14 said in a statement: "The player accepted that he had committed an act of foul play which warranted a red card. The incident was found to merit a mid-range entry point, which indicates a four-week suspension for this offence.

"The Judicial Officer determined that there were factors, including the player’s remorse, which warranted mitigation of one week.

"The player is suspended from participating in the next three meaningful fixtures for which he is fit and available for selection."

Williams was making only his second appearance for the Scarlets since rejoining from Saracens in February 2020.
