Kansas City Chiefs Open Camp With Patrick Mahomes Back on the Field

Patrick Mahomes jogged onto the practice fields at Missouri Western State University this weekend with a brace on his left knee and, by every account out of St. Joseph, the look of a man who never doubted he'd be there. Seven months after a torn ACL and LCL ended his 2025 season, the quarterback got through a full 90-minute practice with no setbacks as Kansas City Chiefs training camp got rolling — and you could practically hear an entire fan base exhale. That's the story that swallows everything else in this week's Kansas City Chiefs news, because a 6-11 team doesn't climb back into the AFC race unless No. 15 is himself again. "I always knew I was going to get back here," Mahomes said afterward. "Just because of my mindset and the people around me."

The knee that decides everything

Let's not overcomplicate the stakes. Mahomes went down in Week 15 against the Chargers last December, and the Chiefs' season went with him. He has been cleared for training camp activities, and Andy Reid is playing it exactly the way you'd expect — "day by day" on the workload, with the medical staff holding the keys. Mahomes says he'll wear the brace throughout camp, and there's real uncertainty about whether he plays in the preseason at all, which would be a first in his career. Nobody in the building seems bothered by that possibility. The target has always been the Week 1 opener against Denver, and everything between now and mid-September is just a controlled ramp.

What's more interesting is Mahomes' own framing of 2025. "I wasn't playing my best football last season before I got hurt," he admitted, which is both honest and true. The Chiefs were sputtering before the injury. The rebuild around him — and it was a genuine rebuild — is designed to make sure a healthy Mahomes isn't dragging a flawed roster uphill again.

Bieniemy is back, and he brought a Super Bowl MVP with him

The two biggest swings of the Chiefs' offseason both walk into camp this week. Eric Bieniemy returns as offensive coordinator after three seasons away, and the numbers behind that reunion are hard to argue with: from 2018 through 2022, Kansas City never finished worse than sixth in scoring or yards with Bieniemy running the room. Without him, the offense sagged to 17th in scoring and 15th in yardage. Whatever you think of how his first stint ended, the fit is obvious.

Then there's the running back. Kenneth Walker III signed a three-year, $45 million deal in March, arriving fresh off a Super Bowl LX MVP performance for the champion Seahawks. He's the kind of every-down threat this backfield hasn't had in years, and how Bieniemy splits his work between the run game and the passing game is one of camp's genuinely fun questions. Around him, Rashee Rice enters a contract year fully cleared after a May knee debridement — he spent the offseason rehabbing at the facility after serving a 30-day jail sentence that ended June 16 — while Xavier Worthy and Tyquan Thornton fight for bigger roles and Travis Kelce comes back for another lap. Even the quarterback depth chart got serious: Justin Fields and Garrett Nussmeier sit behind Mahomes on the 90-man roster, which is a far cry from the thin rooms of years past. If Mahomes' ramp-up hits any turbulence, the drop-off no longer looks like a cliff.

A torn-down, rebuilt Chiefs secondary

The defense is where the front office took a blowtorch to things. Trent McDuffie, an All-Pro, was traded this offseason, and Jaylen Watson left for the Rams. In their place: Mansoor Delane, the cornerback Kansas City took sixth overall, plus veteran L'Jarius Sneed back in the fold, free-agent addition Kader Kohou, and 2025 third-rounder Nohl Williams. That's a lot of new parts at the position Steve Spagnuolo's defense leans on most, and Delane's opening weekend had, in his own words, "ups and downs." That's rookie corner life, and the Chiefs knew what they were signing up for when they spent a top-ten pick on him: growing pains now, a McDuffie-sized role later.

Up front, first-rounder Peter Woods (29th overall) slots in next to Chris Jones, and second-round edge rusher R. Mason Thomas called his first camp practice "a dream come true." If Spagnuolo — who has a long history of fielding top-six defenses — can get the young guys up to speed by October, this unit has more raw talent than any Chiefs defense in a while.

Chiefs injury report: who's limited in St. Joseph

Reid ran through the medical file before camp opened, and the list is longer than you'd like but shorter than it could be:

• Patrick Mahomes (knee) — cleared for camp activities, practicing in a brace, preseason status undecided.
• Rashee Rice (knee) — fully cleared after a May debridement procedure; Reid says he's "doing great."
• Omarr Norman-Lott (knee) — the defensive tackle tore his ACL in Week 7 last season and will likely open camp on the PUP list, though he's expected back at some point this summer.
• L'Jarius Sneed (knee) — managing a chronic issue; the plan is to "take him slowly and gradually get him back into the mix."
• Mansoor Delane (shoulder) — working through his final physical; expect limited participation early.
• John Michael Gyllenborg (knee) — the tight end is still working back from a spring sprain and won't get much early work.
• Ethan Downs (leg) — the defensive lineman was hurt during rookie practices; his status is uncertain.

Where the roster stands after 6-11

It's worth pausing on how strange last season was. The Chiefs missed the playoffs for the first time in a decade, and the response wasn't a teardown — it was a targeted renovation. The core stayed: Kelce, Jones, Worthy, the offensive line's key pieces. The additions skew toward players who've won recently — Walker, defensive tackle Khyiris Tonga, Sneed — because Reid and Brett Veach clearly believe the locker room needed an infusion of guys who remember what January football feels like. On paper, this is a roster built to make 6-11 look like the aberration rather than the trend. Camp is where we find out if the paper holds up — and where battles like the receiver pecking order behind Rice and the back end of the secondary actually get settled.

What's next on the Chiefs' calendar

The schedule from here is straightforward. Quarterbacks and rookies reported on July 24 and practiced through the weekend; the full squad reports Tuesday, July 28, with the first full-team practice Wednesday. The team has 18 open practices planned in St. Joseph over the coming weeks. Key dates:

• July 28 — veterans report to Missouri Western State University.
• Aug. 15 — preseason opener vs. the Rams, 3 p.m. CT.
• Sept. 14 — regular-season opener vs. the Broncos on Monday Night Football at Arrowhead, the first of six primetime games.

So that's the shape of the week: the franchise quarterback is upright, the coordinator who ran the league's most feared offense is back calling plays, and a secondary full of strangers has about six weeks to become a unit. There will be Kansas City Chiefs news that matters more before September — a preseason decision on Mahomes, a 53-man roster with real cuts — but for now, the most important development is the simplest one. The knee held up. Everything else is details.
