Kansas City Chiefs quarterback Patrick Mahomes has been cleared to fully participate in all drills at the start of training camp, marking a significant step in his recovery from a left knee injury that required surgery late last year. The announcement comes nearly eight months after Mahomes suffered tears to both his ACL and LCL during a game at Arrowhead Stadium on December 15, 2025.

Mahomes, 30, expressed optimism about his progress during a news conference at Missouri Western State University, where the Chiefs hold their rookie camp. He acknowledged the challenges of rehabilitation but remained confident in his ability to return to his previous form or even improve. “It’s not over,” Mahomes said, emphasizing the need to continue working hard and proving his readiness to coaches and medical staff. His surgeon, Dan Cooper, gave clearance on July 22 following a follow-up examination.

Chiefs head coach Andy Reid has maintained a cautious approach regarding Mahomes’ potential participation in the preseason, stating that the team will assess his condition on a day-by-day basis. Reid avoided making predictions about whether Mahomes would play, focusing instead on ongoing evaluation. The team is aiming for Mahomes to be ready for the regular-season opener against the Denver Broncos on September 14.

Mental resilience has played a key role in Mahomes’ recovery. He has highlighted the importance of mindset and support systems, mentioning that his family, notably his role as an active father, has served as motivation through difficult periods, particularly during the early phases of rehabilitation. Mahomes also sought guidance from veteran quarterback Tom Brady, who experienced a similar injury, and maintained communication with former teammate Tyreek Hill, who is himself recovering from significant knee injuries.

Throughout his rehab, Mahomes engaged in a friendly competition with free agent tight end Zach Ertz—who also suffered a torn ACL—to maintain motivation. The two exchanged progress videos and compared milestones such as weightlifting achievements and agility drills. Mahomes noted that this kind of competition helped alleviate the isolation that often accompanies the recovery process.

While eager to return to game action, Mahomes recognizes the importance of proceeding cautiously. During training camp, quarterbacks are protected from full contact, and Mahomes will begin wearing a knee brace, although it remains unclear how long he will need it. He acknowledged that the true test of his recovery will come once he takes hits in actual games, which unlike workouts, carry more risk and demand greater knee stability.

Mahomes’ accelerated return from injury is notable given that similar injuries often sideline players for more than a year. He reflected on a prior comeback in 2019 from a dislocated knee, recalling a moment when he notably improvised under pressure—an instance that provided confidence in his mobility and adaptability. This time, his aim is to regain full confidence and improve his performance, including quicker passes and less running, despite having posted career-high rushing yards last season.

As the Chiefs prepare for the upcoming season, Mahomes’ progress stands as a positive sign for the team and its supporters, though the final determination about his playing status will depend on ongoing evaluations by the coaching staff and medical team.
