Félix Auger-Aliassime will finish the 2026 season outside the ATP top 10 after a knee injury forced him to withdraw from the tournaments in Brussels and Basel. The Canadian's absence from both events also ends his hopes of qualifying for the ATP Finals, leaving him facing a disappointing conclusion to a season in which he reached a career-high ranking of world No. 4.
Auger-Aliassime sustained the injury during his fourth-round match against Casper Ruud at the Shanghai Masters. He was forced to retire while trailing 5-2 in the opening set, and subsequent assessments led him and his team to rule out competition for at least the next two weeks.
The withdrawals are particularly costly because both tournaments have been successful hunting grounds for the Canadian. He won in Basel in 2022 and 2023 before claiming the Brussels title last year. Missing the events means losing the opportunity to defend valuable ranking points while his rivals continue competing during the indoor hard-court swing.
The timing is also significant because Auger-Aliassime is defending a substantial number of points from the final weeks of 2025. After reaching the US Open semi-finals, he finished the season strongly with deep runs in Shanghai, Basel and Paris, followed by a semi-final appearance at the ATP Finals. That late-season surge helped establish him among the leading players in the rankings, but he will not be able to reproduce it this time.
Auger-Aliassime confirms withdrawals from Brussels and Basel
The Canadian announced on Saturday that he would miss the next two weeks of competition, explaining that his priority was now recovering from the knee problem sustained in Shanghai. His decision rules him out of the European Open in Brussels and the Swiss Indoors in Basel, two tournaments where he had previously enjoyed title-winning campaigns.
“After injuring my knee during my match in Shanghai earlier this week, my team and I have decided to skip the next two weeks of competition," the Canadian said. "Unfortunately, that means I have to withdraw from Brussels and Basel, two tournaments I have won and where I absolutely love to play. Now, I will focus on my recovery and work hard to return to competition as soon as possible.”
Auger-Aliassime will now focus on his potential return at the Rolex Paris Masters, the final Masters 1000 tournament of the season. However, his participation will depend on the progress of his recovery, and rushing back before he is ready could jeopardise his preparation for the start of the 2027 campaign.
The injury comes at a difficult moment for a player who has traditionally been effective on indoor hard courts. His previous titles in Brussels and Basel demonstrated his ability to produce strong results during this part of the calendar, but the current setback leaves him with limited opportunities to improve his ranking before the season ends.
ATP Finals hopes over as Auger-Aliassime faces ranking decline
Auger-Aliassime's withdrawal from both tournaments ends his chances of qualifying for the ATP Finals in Turin. He sits 15th in the ATP Race, outside the qualifying positions, and will not have the opportunity to collect the points needed to mount a late challenge.
The ranking consequences extend beyond his absence from Turin. Auger-Aliassime is guaranteed to finish the year outside the top 10, ending a run in which he had remained inside that group throughout the season. He was ranked as high as No. 4 after Wimbledon, making the late-season decline a particularly striking change from his position earlier in the year.
Auger-Aliassime's ranking decline is compounded by the points he earned during the final stretch of 2025. He has already failed to defend the points from his US Open semi-final and Shanghai Masters quarter-final runs, accounting for roughly 1,000 points combined.
He also has more than 1,000 points tied to his strong finish to last season, including his Paris Masters final and ATP Finals semi-final appearances. With Brussels and Basel now off his schedule, the Swiss Indoors points are the only ones from that closing stretch he can still defend, provided he is fit enough to compete.

Without the chance to compete in Brussels and Basel, Auger-Aliassime will lose further ground, and a finish outside the top 15 is now expected. Paris remains a possible opportunity to limit the damage, provided his knee allows him to return, but the Canadian can no longer prevent his year-end ranking from falling outside the top 10.
For Auger-Aliassime, the immediate objective is to recover fully rather than force a premature return. His results in 2025 showed how much ground he could gain during the indoor swing, but this time the injury has removed that opportunity and guaranteed a lower year-end ranking than the one he held for most of 2026.

- Vukov is doing this to Lena... AGAIN!!!!! WTA's autonomous collective should be dismantled for allowing Vukov to re-emerge from his hand-slapping suspension. Just ask WTA employees how that's been going lately as they witness his continued verbal abuses. Women's Pro Tennis should start over.
mandoist08-11-2026 - Can't help but suspect Vukov is back to his old self again. Thank you, WTA. Perhaps you can give them a "Battling Couple of the Year Award 2026" ??mandoist08-11-2026

- One step by another step -- WTA continues to 'lose the plot'. Too many hi-tech microphones being installed at most venues!!! Remove them (especially those along the hallways, sidewalks, and pathways throughout the venues. Not to mention (most of all) remove the mic's from the Players/Coaches Box.mandoist06-11-2026

- Don't you just love this young lady!? We fans often expect athletes to be supermen and superwomen, often forgetting that they WILL GET TIRED! I love Alex's perspective. Tiredness for an athlete should never be viewed as a negative, especially if you are healthy, taking care of your body and mental health and putting in the work. What a mature perspective. Good for you, Alex!Rapunzel05-11-2026
- Jess is absolutely correct! But the disrespect is a trait I have noticed in most of the Russian players. Mirra is good but very immature and lacks humility. Conceivable needs to get a handle on that!Rapunzel05-11-2026
- Having spent weeks and weeks through the years on tour, I can say with confidence that Conchita was (is) one of the very few who realize the surprising level of maturity (and sometimes lack of) which Mirra seems to have developed in such a demanding adult world of Pro-Tennis. While at the same time reminding herself (Conchita, that is) that Mirra is still young and developing mentally and physically. The general public may forget at times, or not at all realize, these modern era young athletes do not have a 'normal' Youth. It's a major sacrifice, among countless sacrifices, these athletes must make. People who blow-off that fact are ignorant and unfair when they blurt out, "They choose fame so they have to put up with the intrusions on their lives". No, they do not.mandoist05-11-2026
- Okay... someone with a camera was EAVESDROPPING on a private conversation. Shouldn't that be the point of discussion here? Regardless of the sensationalist crap by media, Pegula (and anyone) has a right to an opinion. There used to be an expectation that private conversations were respected, regardless of 'stardom' and whatever other defensive excuses media tries to shove in our faces. Boo-hoo if feelings are hurt. BTW: Having been employed at various tourney venues, etc., I can't tell you how nasty and offensive players can be when discussing their opponents and colleagues... in "private". Well, I could, but won't. I also challenge anyone to deny what Jessica said is false.mandoist05-11-2026
