The round 15 match between the top-four teams looms as vital for Roos' side on the back of last week's defeat by Collingwood.
The loss stymied the momentum of six wins on the trot for the Swans, but Roos believes his side is wily enough not to let the Hall controversy take their focus away.
"They're a really good group. It's the second time this year something like this has happened, so I don't think they're distracted and I think they're really looking forward to it," Roos said today.
"They are disappointed in their performance last week [against Collingwood] so I'd expect them to play really well on the weekend."
Roos' spearhead stole the headlines again with a one-game suspension following an attempted strike on Magpie defender Shane Wakelin. It followed a seven-game sanction earlier in the season for striking West Coast's Brent Staker.
Hall will take the weekend to mentally refresh by catching up with a friend, a move Roos encouraged him to do. The 31-year-old will be back on Monday for training at the Swans.
"I don't want him to finish his career on a really sour note," said Roos, who reiterated there was no timeframe being put on Hall's return.
Brighter news for the Swans is the return of Adam Goodes, whose one-week ban for rough play saw the dual Brownlow medal winner miss the Magpies loss.
Roos hopes his star onballer will use his spell on the sideline to fine-tune some of his tackling technique. "He's a terrific player. He's not a vindictive player. He's just got to go after the footy, which is not hard to do in AFL. So it's just a technique thing he needs to change," said Roos.
"It's nice to see him playing in the team. It makes life a little easier for the coach. Having a couple of weeks off hasn't really hurt him. I think it might have been good for him."
