Wales star Liam Williams has revealed the extent of the lip injury that has ruled him out of today's match against England.

The mercurial talent would have been likely to start, at either full-back or wing, this evening but will instead by watching from afar.

Around the hour mark in the 18-0 win over Georgia, Williams copped a boot to the mouth as he entered a ruck to help secure possession.

He was replaced by Ioan Lloyd and never returned.

Wayne Pivac later divulged that 15 stitches were required to seal that wound on his lip.

This week, Williams has had difficulty eating and sleeping and the injury has ultimately sidelined him for the biggest of tests.

"I felt my lip, looked down and there was blood everywhere," he wrote in his column for BBC Wales.

"The shock was I thought I had taken a whack in the teeth, but thankfully my gumshield saved them. I have worn one almost since the start of my career.

"I had 15 stitches in total and was fortunate I had expert medical care from the best around and that I was straight on the medical bed with two local anaesthetics - 15 stitches straight in there and away you go.

"At the time I did not think it would rule me out against England. After the game, I did struggle to eat, but because of the local anaesthetic I did not feel anything over the next couple of hours.

"The next morning my lip was huge and I could only eat through the right-hand side of my mouth and that is the same now. Trying to get stuff in is the worst - I have to tilt my head and put food and drink into the side.

"Sleeping has also been tricky. I have woken up twice and my lips have been stuck together from a bit of weeping and blood. So that's not ideal.

"I have had some stick from the boys, but they also saw my lip at the beginning of the week and it looked terrible. I have a modelling career to look after as well!"

Despite being desperate to play against Wales' nearest rivals, Williams had to accept that one more bang on the mouth would reopen the wound.

Should that happen in the first minute, it would leave Wales in a spot of bother and that was not a risk he was willing to take.

He now hopes to be fit for the final game of the Autumn Nations Cup next weekend but will be watching from his living room like the rest of the country today.

"Missing out on playing for Wales against England is devastating. It is one of the biggest fixtures in the game, so it's so tough not to be involved.

"I will be watching the game at home and will be shouting at the television, just like every Welsh rugby fan," he wrote.
