Wales assistant coach Robin McBryde says their players are conscious of the probable effects of any lapses during the World Cup.
After having a three-match prohibit for a dangerous attack australia wing Reece Hodge will miss Sunday’s Pool D showdown from Wales.
When they were cited for tackles during the victory over Russia on Tuesday samoa gamers Rey Lee-Lo and Motu Matu’u are awaiting hearings.
Although he confessed that cans affect but McBryde is hopeful Wales will escape censure that is these.
“Players are aware of the sanctions, and we will not see too many of them throughout the World Cup,” explained McBryde.
“it is a hard one. Anybody who has played football understands that things happen within an split-second.
“The aggressive character and collision dominance that’s spoken about in attack and defence means you’ve got to be bang on the money.
“It is easier said than done when the exhaustion has put in. When mistakes are made, gamers are exhausted and if the requirements are humid, that is.
“Things happen very fast at a game of rugby, and also a few calls are tough and others are not so hard to make.
“It’s an ever-changing planet in rugby with all the influence the TMO [television match official] has. Players know that they might have to do the utmost to maintain their focus and attention to not make silly errors.”
Hooker Ken Owens and centre Hadleigh Parkes both took part in training after suffering knocks on Monday during the 43-14 victory over Georgia.
Lock Bradley Davies, who has come in for the injured Cory Hill, has arrived in Japan and was also involved in coaching.
Sunday’s game in Tokyo is place to choose which team wins Pool D, with Wales expecting to follow their win from Australia 10 months ago with a success, though 13 successive defeats against the Wallabies continued that victory.
McBryde included:”Everybody realises the magnitude of this game. We know we can beat them, but this is a tournament.
“We can take heart in the truth that we know we could defeat them, but it is distinct conditions. It’s going to be a good battle.”
While recognising the danger of Australia, McBryde highlighted the Wales openside flanker Justin Tipuric must cause difficulties for the Wallabies.
“It’s invaluable to have somebody like Justin from the ranks, he brings that atmosphere of calmness. He does not say a lot but when he talks it takes a great deal of weight,” said McBryde.
“I know that he didn’t acquire man-of-the-match award for the Georgia game but in my opinion he deserved it.
“To have somebody like Justin using the experience he’s obtained, supporting him to share that with the team this week, it’s just great really and also leaves my job as a mentor a lot easier.”
