Details of the injury were not disclosed beyond confirmation that the back issue forced the withdrawal. The 23-year-old from Montreal had been listed as the top Canadian in the men’s singles field and was scheduled to play in the second round, facing France’s Titouan Droguet if he had advanced through the opening match. The withdrawal leaves Droguet to progress in the draw without a direct matchup against Auger-Aliassime.
The National Bank Open, part of the ATP and WTA tours, is staged in Montreal and has drawn a strong international field. Auger-Aliassime, ranked among the world’s top players, has been a regular title contender on the tour and has enjoyed significant success in recent seasons, including deep runs at major tournaments. His absence is a notable development for local fans and for the tournament’s competitive balance.
Representatives for Auger-Aliassime indicated that the decision to withdraw was made after medical assessment of the back issue. No timetable for a potential return to competition was provided, and it remains unclear when the Canadian star might resume training or participate in upcoming events.
The National Bank Open organizers issued a brief statement acknowledging the withdrawal and wishing Auger-Aliassime a swift recovery. They noted the tournament would continue with the remaining field as scheduled.
Fans and officials expressed disappointment at the home event’s first-round exit for the top-ranked Canadian, but expressed hope that Auger-Aliassime would recover quickly and be back on the court soon. The player has not publicly commented beyond the withdrawal notice issued by his team. Further updates are anticipated as medical evaluations progress.
