Scotland back-row Josh Strauss admitted he was angry for his team-mates Ross Ford and Jonny Gray after the pair were suspended by World Rugby.
Ford and Gray have been slapped with three-week bans in a decision that has caused outrage among social media from ex-players and supporters.
Strauss said it was tough to hear the news but stressed the team must remain focused on the job in hand, which is facing Australia on Sunday.
"We're all very disappointed for them, we are a really close group of guys and know each other really well and they are two timid guys. I'm not the one who makes the call though. Obviously I'm disappointed for the group and it is tough on them," said the Scotland forward on Wednesday.
"When I heard it I was angry for them. I imagined myself in their shoes and imagined what it would be like if it was me. But that is good as it motivates me and I want to put in a performance for them and make them proud.
"We've dealt with things like this in the past and it will make us better. We'll bank the thoughts and try and use them."
On what Scotland need to beat Australia in the quarter-final on Sunday, Strauss added: "Belief. You don't come into any competition not thinking or believing you can win. I've played a few of their players in Super Rugby in the past and anyone can be beaten. We've earned the right to play them and we're going to do our best at the weekend."
"The goal is to win at the weekend; the focus is to win the game. We've achieved so much as a group together and won't let anything stand in the way of what is probably the biggest game of our careers."
