Liam Williams has revealed the stick Gareth Davies received from his Wales team-mates after his 'brain fart' moment against Ireland last weekend.
Davies inexplicably kicked possession away with around 10 seconds left on the clock as Wales were hanging on for victory. It led to an anxious final few minutes as Ireland battered away at the Welsh defence before Wayne Pivac's side finally claimed a 21-16 win.
Writing in his BBC column, Williams revealed he was winding Davies up within minutes of the final whistle.
"We were all relieved at the victory at the end, none more so than Gareth Davies. Now, as you imagine, we have all given him a bit of stick," he said.
"He has just had a bit of a 'brain fart' moment. Those were his actual words.
"I know Gareth well and I can tell you he was kicking himself more than anyone and he was also reminded about it by the coaches afterwards.
"It's always a balancing act when to wind somebody up after the game following an incident like that. When is too soon?
"I suppose it depends on whether the mistake has cost the game or not. Luckily on this occasion it did not as we defended well at the end and Ireland fly-half Billy Burns missed the kick to touch.
"So on this occasion, I gave him a bit of stick in the changing room straight after the game. It was on the sly and I felt comfortable because I know him well.
"The most important thing is how he reacts and he has shown his class so many times on the world stage. So I expect him to have a big game against Scotland leading the forwards around."
The Wales squad has been ravaged by injury over the past week, with a number of players ruled out of today's Scotland match.
But it is the cruel injury to flanker Josh Macleod, who ruptured his Achilles in training an hour after being named in the side for his first cap, that has really struck a chord.
Macleod also missed out on playing in the autumn after injuring his hamstring following his squad call-up. He now faces six months out after this latest incident.
Williams added: "Six-day turnarounds are tricky and there are quite a few players on the sidelines at the moment. That's the nature of the sport we play and we have a big enough squad to cope with a few boys coming in.
"There must be one special mention though to my Scarlets team-mate Josh Macleod who has been so unlucky.
"He is told he will start and win his first cap for Wales, but less than an hour later he has ruptured his Achilles in training and is out for six months.
"This comes after he was picked last autumn, but missed the internationals through injury. I have been speaking to him over the last 24 hours and it feels as if he is a man down.
"He has been one of the in-form players for Scarlets over the last couple of seasons and has been outstanding. I am devastated for him, but I am sure he will come back a better player."
