How Patrick Mahomes turned a season-ending ACL-LCL injury into a record-setting comeback push as the Chiefs carefully prepare him for the season(Getty)Patrick Mahomes’ 2026 comeback seemed difficult from the moment he left the field against the Los Angeles Chargers on Dec 14, 2025. The Chiefs QB suffered a torn ACL and LCL in his left knee while scrambling late in the game, ending his season and forcing him into a lengthy rehabilitation. He underwent surgery the next day, with both ligaments repaired. For a quarterback whose game depends heavily on movement and improvisation, getting back to full strength in time for the new season was a major challenge.Mahomes attacked the recovery instead of waiting for it to happen. Andy Reid recently revealed that the quarterback spent seven hours a day working on his rehabilitation during the offseason. That effort helped Mahomes reach full training-camp clearance in July, roughly seven months after the injury. He has since taken part in every full-team practice without an obvious restriction, giving the Kansas City Chiefs a much more positive picture of his recovery than many expected when he first went down.How did Patrick Mahomes recover from the ACL-LCL injury that ended his 2025 season?Patrick Mahomes was hurt late in Kansas City’s loss to the Chargers when he scrambled and planted on his left leg. His knee buckled, and he immediately went down before being helped from the field. The injury ended not only his season but also Kansas City’s playoff hopes. The Chiefs finished 6-11, their first losing season of the Mahomes era.The quarterback then spent the offseason focused on getting his knee ready for football again. Reid’s revelation about a seven-hour daily rehabilitation routine showed the extent of that work. Mahomes was at the Chiefs’ facility for hours every day, progressing through the physical demands required to return from the ACL and LCL damage.Chiefs HC Andy Reid has repeatedly praised Mahomes’ commitment. The coach described his quarterback as being “all in” and said he was working every day. The seven-hour routine was not simply about getting cleared for camp. Mahomes had to rebuild strength, movement and confidence in the knee before he could start testing it in football situations.That work paid off when Mahomes was cleared for full participation at training camp. The clearance came around seven months after surgery, allowing him to take part in all of the team's practice periods instead of following a restricted schedule.For Mahomes, the next test was not rehabilitation equipment or individual drills. It was doing the things he normally does when a play breaks down.How has Patrick Mahomes performed at Chiefs training camp and what are analysts saying about his progress?Patrick Mahomes has looked increasingly comfortable during camp. After 13 practices, KCTV5 reported “no visible signs of trouble with his surgically repaired knee”, while other camp reports have noted that he has been moving in and out of the pocket without an obvious limitation. He has been on the field every day since Kansas City began its full-team work on July 29.One of the clearest tests came when Mahomes scrambled during a fourth-down play. He ran, changed direction and attempted to pitch the ball instead of simply protecting himself and taking what the defence gave him. The play showed that his natural instincts are returning, but Mahomes also recognised that he needs to be smarter with those instincts while his knee continues to regain its full strength.“I’m trying to hold myself back because I’m just a competitor,” Mahomes said. “I like competing.”He then explained exactly how he plans to handle the rest of his recovery: “I’m not going to lose who I am, but I’m going to try to keep myself smart and keep myself in position to be out there for my teammates.”The star-QB also admitted that he should have handled the fourth-down situation differently. He said that if he could not scramble for the first down, he needed to throw the ball and give another teammate an opportunity. He described it as part of learning what he can do with the knee now and becoming faster as he gets more comfortable.That is an important part of the current evaluation. Mahomes does not appear to be avoiding movement. He is learning how much movement he can safely use and when he needs to make the less aggressive decision.Analyst Jason McCourty has also discussed the cautious approach around Mahomes, while camp observations continue to suggest that the quarterback is progressing well. The fact that Kansas City has cleared him for full work while still controlling his preseason workload shows the difference between being physically cleared and being given unnecessary game exposure.Why are Andy Reid and Patrick Mahomes taking the preseason slowly despite his strong training-camp return?The Chiefs are not treating Mahomes’ camp progress as a reason to rush him into preseason action. Reid has confirmed that Mahomes will not play in Saturday’s preseason opener against the Los Angeles Rams. Justin Fields, Garrett Nussmeier and Chris Oladokun are expected to handle the quarterback snaps instead.That decision follows Reid’s earlier comments that he was leaning against playing Mahomes in the opener and was not even certain whether the quarterback would play in either of the Chiefs’ remaining preseason games.Mahomes is prepared to follow the coaching staff’s decision. He said he would prepare as though he were playing but would accept whatever Reid decided was best for his recovery and the season.“I’m for whatever Coach says,” Mahomes said. “I’m going to prepare to play. He hasn’t told me anything. I’ll prepare to get myself ready. If not, I’ll be as locked in as I am during games and try to get myself ready to go for the season opener.”The approach makes sense because Mahomes has already passed the biggest checkpoint: he is back in full training-camp work. There is little value in exposing a recently repaired knee to unnecessary preseason hits when the Chiefs' priority is having him ready for the regular season.Kansas City opens its 2026 campaign against the Denver Broncos on September 14. That is the game that matters. Mahomes can use the remaining weeks to continue building strength, speed and confidence instead of trying to prove anything in August.His recovery has already moved faster than the timeline many would have expected after an ACL-LCL injury. Now the Chiefs are making sure the final stage is handled carefully.Patrick Mahomes spent seven hours a day earning his way back. He is now doing what he has always done in camp: competing, scrambling and creating plays. The difference is that he is also learning when to stop himself. That understanding is truly the most important part of his return.
