Wales hooker Ken Owens said his side were "shell shocked" by Rob Howley's betting affair, but said they will use it as a "galvanising force" going into their World Cup opener against Georgia.
Assistant coach Howley was sent home from Japan earlier this week for an alleged breach of World Rugby's betting regulations.
Owens, who is chairman of the Welsh Rugby Players' Association, revealed the Wales squad had a pre-arranged World Rugby integrity briefing - which are given to all World Cup nations - a day after the Howley matter was announced.
Former Wales fly-half Stephen Jones, who is replacing Howley, has arrived at the squad's Toyota City base and will be part of training heading into Monday's encounter.
Lock Adam Beard, meanwhile, is due to link up with the squad imminently after remaining in Wales last week to have his appendix removed.
Neither Beard nor his fellow lock Cory Hill, who is recovering from a stress fracture in his leg, are expected to be involved against Georgia.
