The Kansas City Chiefs can’t seem to escape the weirdness that has surrounded the team’s offensive line during the 2026 NFL season. Their Week 4 matchup against the Las Vegas Raiders added a new chapter.

When the Chiefs’ offense took the field to start the game, backup offensive lineman Mike Caliendo lined up in place of starting left guard Kingsley Suamataia. That alone might not seem strange. It would make sense if the team had announced that Suamataia was ill or had suffered an injury during warm-ups. However, Kansas City made no such announcement.

In fact, the team told reporters in attendance that Suamataia’s absence from the starting lineup in Week 4 was a “coaching decision.”

Mike Caliendo held up early, but the second half told a different story

Caliendo filled in admirably in the first half, allowing no pressure through two quarters. His success as a pass protector deteriorated after halftime, though. He allowed a sack on quarterback Patrick Mahomes on a second down in the third quarter. It put the team at 3rd-and-18, with virtually no shot of converting.

Speaking to reporters after the game, Chiefs coach Andy Reid didn’t offer much of an explanation for benching Suamataia against the Raiders. Reid opened his press conference with a statement on the topic, saying that the decision and the reason for it would stay between him and his starting left guard.

“As far as the Kingsley (Suamataia) thing goes, so before you guys ask, that’s between Kingsley and I,” Reid told reporters. “But we’ll figure it out, and down the road we’ll be better as a team for it, and Kingsley will be better for it.”

That wasn’t a good enough explanation for the media members in the room. One of the first questions Reid fielded was about that decision. He doubled down and was a little curt with reporters who were just trying to understand.

“Yeah, that’s between Kingsley (Suamataia) and I,” Reid said. “I might have stuttered when I said that, but that’s what I meant. Kingsley and I will take care of that.”

A pattern of strange situations up front for Kansas City Chiefs

This is just the newest chapter in a string of odd situations surrounding the K.C. offensive line this season. For starters, starting left tackle Josh Simmons still hasn’t played through four weeks because of what the team is calling a bulging disc in his back. Simmons hasn’t practiced since mid-August. It took until last week to get a straight answer on the type of injury that he’s been dealing with.

Now there’s a mysterious reason behind the benching of the team’s starting left guard. Entering Week 4, Suamataia was the league’s top left guard in pressure rate, allowing pressure at just 3.8%, per NFL Next Gen Stats. Benching a player performing at that level doesn’t add up.

Maybe Coach Reid has good reasons. Perhaps a team rule was broken. Maybe Suamataia was supposed to do something and didn’t. Whatever the case, the decision to sit him down in Week 4 could have backfired. It didn’t, but it did put Mahomes at undue risk in just his fourth game back from a season-ending knee injury.

This mystery will only fuel conspiracy theories, fair or unfair to Coach Reid and Suamataia.

Patrick Mahomes weighs in on the left guard situation

Mahomes also spoke to reporters about the situation. He explained that his starting left guard knows how important he is to the team. Mahomes added that the Chiefs have plenty of trust in Caliendo, who started in a Super Bowl for Kansas City just a few seasons ago.

“Yeah, I mean Kingsley (Suamataia) knows how important he is to the team, and so like like coach, he’ll keep it between him and Kingsley,” Mahomes said. “But at the end of the day, man, we have a guy like Mike Caliendo who’s played in a lot of big games and had a lot of reps. He stepped right in and did a great job against a really good defensive line, and so I have a ton of trust in him. And then we’ll get Kingsley back in the fold here soon.”

All in all, the Chiefs escaped Week 4 with a victory. That said, it definitely feels like they made things harder on themselves by keeping Suamataia on the sideline. The team could have easily put him in for the second half. Instead, Kansas City left him on the sideline, watching rather helplessly as his teammates played without him.

Maybe that’s a lesson he needed to learn. As Reid suggested, both the team and Suamataia could be better for it. The question is whether the Chiefs’ offensive line can finally put the strangeness behind it as the season rolls on.
