Kansas City Chiefs quarterback Patrick Mahomes was diagnosed with a "mild high-ankle sprain" following Sunday's win over the Cleveland Browns, according to Ian Rapoport of NFL Network, an injury that forced him out of the contest in the fourth quarter.

Pro Football Talk's Mike Florio and Rapoport reported that Mahomes is expected to be "week-to-week" moving forward.

Mahomes was uncertain about his timeline when discussing the situation after the game with reporters:

"It's hard to say right now. You still [have the] adrenaline rolling and usually it's kind of the day after when you kind of get a good sense of it. I feel like I could have finished the game in different circumstances, but I thought the smart decision ... was to put Carson Wentz in.

"You just do what you have to do to get back, and I think that's the most important thing. And now we just get back to the rehab part, the treatment part, and try to get ourselves ready on a short week against a good football team."

Mahomes was listed as questionable but did not return with the Chiefs closing out the 21-7 win.

After the game, Mahomes walked out of the locker room before leaving on a cart:

Mahomes, 29, has accomplished just about everything a quarterback would want in the NFL, and did so within his first six seasons. He's a three-time champion, two-time MVP, two-time first-team All-Pro selection and six-time Pro Bowler.

Under his watch, the Chiefs have reached the playoffs in six straight seasons and coming into Sunday were 86-23 in his regular season starts.

Not that it's all been smooth sailing. The 2023 season presented its difficulties as the Chiefs never replaced the impact of Tyreek Hill after he was traded to the Miami Dolphins two seasons ago. In 2022, JuJu Smith-Schuster and Marquez Valdes-Scantling led the passing attack, and while neither offered anything close to the impact of Hill, both were solid enough en route to a title.

But Smith-Schuster signed with the New England Patriots that offseason and Valdes-Scantling was largely an afterthought, so Mahomes mixed the ball around to a bargain bin of wideouts that included Rashee Rice, Kadarius Toney, Skyy Moore and Justin Watson.

Granted, Travis Kelce remained the best tight end in football and Mahomes creates plenty of plays all on his own. But Kansas City's offense wasn't as unstoppable as past. That made the Chiefs seem vulnerable, at least until they won another Super Bowl.

Kansas City appeared to retool the receiver position ahead of the 2024 campaign, adding players like Marquise Brown and Xavier Worthy. But when Rice was lost for the season and Brown missed significant time, the unit was again decimated until DeAndre Hopkins was added in a trade.

Any serious injury to Mahomes is a death blow for the Chiefs. He has largely avoided lengthy stints on the sideline during his career due to injuries, though Carson Wentz is at least an experienced option as the backup.

But Kansas City's fate rests squarely on the right shoulder of Mahomes. As he goes, so go the Chiefs.
