Josh Adams will miss the first two rounds of the Guinness 6 Nations following a breach of the Welsh Rugby Union's Covid-19 protocols.
A WRU statement read:
Wales squad member Josh Adams has been released from the Welsh training camp, having been suspended for the first two matches of the 6 Nations 2021 following a breach of COVID-19 protocols.
The full squad were released from camp on Saturday afternoon, and unfortunately on Sunday January 31, Josh attended a gathering with his immediate family present.
The squad linked back up on Tuesday at the Vale Resort and the breach was immediately raised and acted upon.
"We are extremely disappointed with the breach and have acted robustly and swiftly to take all appropriate measures," said Wales head coach Wayne 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."
All members of the national squad have received extensive COVID-19 protocol briefings and education. 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.
The latest round of COVID-19 testing results (today) for the national squad all returned negative.
Josh Adams said:
"I would like to apologise unreservedly.
"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 teammates and to our supporters for my mistake."
