Kansas City Chiefs quarterback Patrick Mahomes underwent successful surgery Monday night in Dallas to repair the tear in his left ACL, the team announced.

The surgery was performed by Dr. Dan Cooper, the Dallas Cowboys' head team physician. A league source told ESPN that Dr. Cooper also repaired the torn LCL in Mahomes' left knee, confirming a report by NFL Network.

According to the Chiefs and the story, Mahomes "will begin his rehab process immediately." Mahomes was injured with less than two minutes remaining in Sunday's 16-13 loss to the Chargers. The story went on to say the typical recovery for such an injury is about nine months, meaning Mahomes will miss the team's offseason program, and his availability for the start of next season is in question. The 2026 NFL season opener is Sept. 10, the story said.

Backup quarterback Gardner Minshew, a five-year veteran, is expected to be the team's starter for the final three games of the regular season.

That stretch will serve as an audition for Minshew to remain with the Chiefs for next season, the story would add. "I've got a ton of confidence in Gardner," Reid said in the story. "I've watched him play with other teams, he's started in the league, and our guys have confidence in him."

After suffering a season-ending injury on Sunday, Chiefs quarterback Patrick Mahomes is seeking out more information on his injured knee before finalizing a course of action to repair it.

Kansas City head coach Andy Reid told reporters in his Monday news conference that Mahomes is going to get a second opinion in Dallas from Cowboys team physician, Dan Cooper, the story went on to say. Reid added that Mahomes and the team does not currently fear that there was more damage suffered to the quarterback’s knee beyond the ACL.

An MRI Sunday confirmed a torn ACL for Chiefs QB Patrick Mahomes, the team announced.

Mahomes tweeted, "Don't know why this had to happen. And not going to lie it hurts. But all we can do is trust in God and attack every single day over and over again. Thank you Chiefs kingdom for always supporting me and for everyone who has reached out and sent prayers. I will be back stronger than ever."

The Chiefs and Mahomes are exploring surgery options.

Sunday ended up a nightmare day for the Chiefs, losing their star quarterback and being eliminated from playoff contention at 6-8. Gardner Minshew came on in relief and went 3-of-5 for 22 yards with an interception.

Chiefs QB Patrick Mahomes will undergo an MRI on his knee Monday, head coach Andy Reid said Sunday.

Mahomes injured his left knee late in the fourth quarter of the Chiefs’ 16-13 loss to the Los Angeles Chargers. As a result of the loss, coupled with wins by the Jaguars, Bills and Texans, the Chiefs will miss the postseason for the first time since 2014. We’ll see if that plays into how long Mahomes will be out for, if at all, but this is certainly unfamiliar territory for the Chiefs, to be out of playoff contention with three weeks left. Gardner Minshew came on in relief of Mahomes and threw an interception to seal the game for the Chargers.

Chiefs WR Rashee Rice was limited on Monday. RB Isiah Pacheco was listed as full.

Rice is dealing with a hamstring issue and this will be worth monitoring on a short week. It looks like Pacheco (knee) will return to the lineup after a full practice, which will cut into Hunt's workload. Also, Mahomes is dealing with a groin injury, but was also listed as having a full practice.

Chiefs WR Rashee Rice’s six-game suspension is now over and he is eligible to play Sunday vs. the Raiders.

The Chiefs and Mahomes get back another weapon for their offense which looks to be clicking, at least at times this season, especially this week when knocking off the Lions on Sunday night. When we last saw Rice to start 2024, he collected 24 catches on 29 targets in three games, piling up 288 yards and two touchdowns. It may take a little time to get Rice up to speed, but Rice was with the team in training camp before his suspension started which should only help. The Chiefs host the Raiders in Week 7 in an early Sunday game.

Ahead of Sunday's game against the Baltimore Ravens (4:25 p.m. ET, CBS), the Chiefs are optimistic Xavier Worthy will be able to play a limited role for the offense while wearing a small harness. Patrick Mahomes and HC Andy Reid say they are confident the Chiefs can continue to be successful on deep passes with Tyquan Thornton running routes alongside Worthy. By Week 7, Mahomes' dropbacks could feature him having a combination of quality options -- such as Travis Kelce, Thornton, Worthy, Rashee Rice and Hollywood Brown.

Slowly the Chiefs offense is starting to get healthy and back to what everyone envisioned at the start of the season. Worthy has a chance to play in Week 4 but the team is already saying he'll be limited, so fantasy owners will want to monitor just how much Worthy will play or maybe in what situations.

He saw just four games his sophomore season before tearing up his knee chasing down a defender after a Patrick Mahomes interception. But the good news amid the bad news: Rashee Rice did not tear his ACL but his LCL, which meant a shorter recovery time. Thus, the wideout was back on the field this spring for the Chiefs, and coach Andy Reid said he expects him to be full-go for the start of training camp. Rice’s return will be crucial for an offense looking to rediscover its explosiveness. — Zak Keefer

Keefer went on to say Rice had 938 receiving yards as a rookie in 2023 and was building off that early in Year 2. Kansas City has been waiting for a WR1 to step into the role vacated by Tyreek Hill in 2022. He’s not Hill, but Rice might be this team’s best bet. He has future Pro Bowler written all over him, according to Keefer. Rice was good his first four games and seemed on his way to a bust-out year last season. Rice seems to be a late third round target in 12-team leagues so far this summer.

“I think I’ll be in a better place ankle-wise,” Patrick Mahomes said, via Adam Teicher of ESPN.com. “Obviously the body’s going to be sore just with a short week and everything like that, but I think the ankle should be in a better place. We’ll see in practice, but as far as how I felt after this game compared to the one before, I’m definitely in a lot better place.”

The short week could be a factor but it's hard to doubt Mahomes as this point. He bounced back rather nicely in Week 17, throwing for a TD and then running for another. The Chiefs play on Christmas Day against the Steelers.
