The Chiefs and Broncos are set to open the 2026 season with a Week 1 matchup that doubles as a return date for two AFC West quarterbacks who spent the back half of 2025 working their way back from major injuries.
Patrick Mahomes and Bo Nix both had their seasons cut short, both went under the knife, and both are now back in position to take the field when the spotlight turns to Monday Night Football. The path each one took back was different, but the result is the same: they’re ready to move forward after long layoffs.
Mahomes’ setback came in Week 15, when his 2025 season went from rough to brutal in a loss to the Chargers. He tried to escape a defender, got his left leg caught in the turf as he went down, and left with a torn ACL and torn LCL. The injury ended his season on the spot.
He had surgery on Dec. 15, 2025, just one day after the injury. At the time, the recovery window was framed as roughly nine months at the optimistic end, with a year as the more cautious estimate.
Chiefs vice president of sports medicine and performance Rick Burkholder said in December, "Every player is different. Every sport is different.
Every position is different," Chiefs vice president of sports medicine and performance Rick Burkholder said in December. "[Mahomes] is so in tune to what he does, he does it a little quicker.
Ballpark on this is nine months, but it could be a month or two more, a month or two less."
Kansas City cleared Mahomes for full participation during July training camp, and when he returned to the field, he was wearing a compression sleeve and brace on his left knee.
By Monday, it will have been nearly nine months to the day since the ACL tear. Mahomes will have missed only two games because of the injury, and his seven-month return-to-practice timeline stacks up well against other quarterbacks who came back from ACL tears, including Joe Burrow, Deshaun Watson and Robert Griffin III. The Chiefs are expected to be careful with him as he tries to settle back in after the longest absence of his career.
Nix’s road back began after Denver’s AFC divisional win over the Bills on Jan. 18.
On the Broncos’ final drive, he landed awkwardly after moving to the side on a quarterback sneak meant to take pressure off kicker Wil Lutz, and he suffered a right ankle fracture. Nix stayed in the game and did not miss a snap.
Sean Payton didn’t realize anything was wrong until he congratulated Nix on the sideline after Lutz’ game-winning field goal, according to ESPN’s Sal Paolantonio.
Doctors later determined that Nix had broken a bone in his ankle, and he was ruled out for the rest of the postseason. That pushed Jarrett Stidham to the top of the depth chart for Denver’s AFC Championship game against the Patriots. Nix had surgery less than a week after the divisional round ended, and Payton said he expected him back in Broncos colors by the start of the 2026 season.
Nix was back on the field by the end of August, and in Denver’s preseason loss to the Packers he threw a touchdown. He also had another surgery in April to clean up bone spurs and was mostly kept out of team drills during the Broncos’ offseason program, though he did throw on a limited basis during June’s mandatory minicamp.
After that preseason appearance, Nix said, "[I was] excited, not really nervous," Nix said after his preseason cameo, according to ESPN. "I knew it was just going to be a few plays and wanted to see the production."

Sean Payton Tries To Shut Down Strange Broncos Drew Brees Speculation
When Bo Nix went down in the AFC Championship game, the Broncos were already dealing with the kind of quarterback uncertainty that can turn even the strangest rumor into something that gets legs fast. That was the backdrop for the chatter tying Drew Brees to Denver, a story that made sense only in the broadest, most desperate sense: a retired franchise icon with deep ties to Sean Payton and a team suddenly looking for answers on the biggest stage.
Payton moved to cool it off quickly, saying Brees had reached out to former Broncos assistants Pete Carmichael and Joe Lombardi, but the idea never made its way to him directly and never moved beyond that. Even so, the mere existence of the conversation raises a separate concern because Brees remains on the Saints' reserve retired list, which puts any flirtation with a comeback in a very delicate spot under NFL tampering rules.

Broncos Defense Has A Week 2 Problem Fans Can't Ignore
The Broncos loss to Kansas City wasnt just about missed chances on offense or a few breakdowns here and there on defense. It was the tackling. Denver missed 29.8 percent of its tackles in the defeat, the worst tackling rate in an NFL game since 2018, and the issue showed up all over the field as the Chiefs kept turning routine plays into extended gains.
Several Broncos, including Talanoa Hufanga and Justin Strnad, acknowledged the problem afterward, and the fix sounds straightforward enough in theory: more tackling work before the next game. Still, the damage was obvious against Kansas City, especially with Walker piling up 144 yards after contact, a reminder that Denvers defensive front and second level will be under scrutiny until it proves the missed tackles were a one-game collapse rather than a pattern.

Mahomes Just Added Another Worry For Broncos Fans
Patrick Mahomes was back in uniform for Kansas City on Sunday, nine months after surgery to repair a torn ACL and LCL in his left knee, and the Broncos saw plenty of the version of him they have spent years trying to slow down. He scored on a rushing touchdown and helped the Chiefs roll past Denver 31-10, a reminder that even after a major knee injury, Mahomes can still change a game with his legs as well as his arm.
For Broncos fans, the postgame tone probably offered the most unsettling part of all. Mahomes said he felt good after returning, while also admitting there was some nervousness about taking another hit to the leg, which is exactly the kind of concern Denver would rather not hear as the rivalry moves forward.
