Wales winger Josh Adams has been suspended for the opening two games of the Six Nations following a breach in Covid-19 protocols.
The decision follows after the 25-year-old attended a family gathering on Sunday - a day after the Wales squad members were released from the training camp.
The squad members assembled again on Tuesday at their Vale Resort base during which the issue was addressed.
Wales head coach Wayne Pivac was disappointed with the news but insisted that the right decision was made considering the safety of the squad members.
"We are extremely disappointed with the breach and have acted robustly and swiftly to take all appropriate measures," said Pivac.
"All players and management have received detailed briefings and education regarding our protocols, and everyone has a responsibility to abide by the rules.
"On this occasion, Josh has made an error of judgement, he made a mistake and he has shown immediate remorse.
"He was present at a small, immediate family gathering to celebrate a milestone with those close to him, but that is against the rules and action had to be taken."
Adams, who has played 29 times for Wales between 2018 and 2020 apologised for his actions.
"When out of camp, at the weekend, I made an error of judgement. I attended a small gathering of immediate family to celebrate a family milestone.
"It was wrong to do this. I'm aware that everyone needs to follow the rules and being in the public eye I have a responsibility to lead by example and I've fallen short on this occasion.
"I'd like to apologise to my team-mates and to our supporters for my mistake."
Meanwhile, a statement released by the Welsh Rugby Union said that Adams will go through the board's Covid programme before rejoining the squad.
"We will continue with our programme, which has been very effective to date, and remind everyone of their responsibility to not only adhere to the extensive measures in place but also to set an example.
"We will work with Josh in relation to his integration back into camp following a further testing and re-education process."
