Injury woes remain one of the defining storylines of the 2026 tennis season, and the upcoming Canadian Open is the latest casualty. With the combined ATP/WTA 1000 event set to run from August 1-13, the men's draw in Montreal, the women's in Toronto, six notable players have already confirmed their withdrawals before the tournament even begins.

On the WTA side, five players are out. The highest-profile late addition is world No. 6 Karolina Muchova, the Wimbledon finalist who revealed on social media that she needed a minor surgical procedure following the grass-court major. The 29-year-old Czech expressed genuine disappointment, noting she had been eagerly anticipating her Toronto debut before putting recovery ahead of competition.

Joining Muchova on the sideline are Emma Raducanu, Hailey Baptiste, Dayana Yastremska, and defending champion Victoria Mboko. The 19-year-old Canadian, who lifted the trophy in Montreal last year alongside Ben Shelton on the men's side, has been sidelined since sustaining a knee injury in her opening-round match at the Queen's Club Championships last month.

For the ATP draw in Montreal, Carlos Alcaraz remains the sole withdrawal so far, though it's a significant one. The seven-time Grand Slam champion has been absent from competition since April, sidelined by a right wrist injury. The 23-year-old Spaniard's extended absence has been one of the most closely watched situations in men's tennis this summer.

With so many big names missing, the path to the title could open up for players deeper in the draw, an intriguing dynamic for bracket hunters everywhere. TennisDraw users will want to revisit their Canadian Open picks carefully given this rapidly shifting field.
