On 9 August 2023, on the eve of the Premier League season, Buendía suffered what was described as a "significant knee injury" in training and would require a scan and treatment from a specialist.[31] The injury was confirmed to be anterior cruciate ligament injury which required surgery and meant that Buendía missed the entirety of the 2023–24 Aston Villa season. Buendía returned to training in May 2024 after 9 months out.[32] Buendía's return to football came on 27 July 2024, almost a year to the day of his injury, in a pre-season friendly against Columbus Crew.[33]
