The squad linked back up on Tuesday at their Vale Resort base and the Welsh Rugby Union say the breach was immediately raised and acted upon. Wales head coach Wayne Pivac said: “We are extremely disappointed with the breach and have acted robustly and swiftly to take all appropriate measures.
“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.”
Cardiff Blues speedster Adams has won 29 caps and scored 14 Test tries. The 25-year-old was the top try-scorer at the 2019 World Cup in Japan with seven tries.
