The Kansas City Chiefs have made at least one roster move ahead of their Week 7 matchup with the Seattle Seahawks on “Sunday Night Football.”

As I predicted just yesterday, the Chiefs have signed practice squad wide receiver Andrew Armstrong to the 53-man roster. This comes after the team placed LT Josh Simmons on injured reserve.

Signing Armstrong rewards a practice squad player who stood out in Week 6 against the Los Angeles Chargers. It also follows a training camp and preseason that put him close to making the initial 53-man roster. In a corresponding move, Kansas City re-signed running back Nate Carter to the practice squad.

Andrew Armstrong earned his spot against the Chargers

Armstrong played 42 offensive snaps in the Week 6 game against Los Angeles. He caught one pass on two targets for 13 yards. The box score doesn’t tell the whole story, though.

The 6-foot-4 and 210-pound receiver really stood out as a perimeter run blocker. He cleared the way for RB Kenneth Walker, even on snaps when he wasn’t explicitly asked to run block. That kind of effort tends to get noticed by coaches, and it clearly did in this case.

Armstrong proved in Week 6 that he belongs on the 53-man roster. He also showed the team that it can trust him to execute in big moments. That trust matters right now, with fourth-year WR Rashee Rice ruled out for the second consecutive game with a hamstring injury.

The Chiefs need more from Armstrong in Week 7

Kansas City will need more from Armstrong this week. He received the third-most snaps of any receiver on the 53-man roster against the Chargers. Rookie WR Cyrus Allen is expected to keep growing and earning more snaps, but Armstrong is clearly part of the puzzle, too.

The team is also navigating what could ultimately be a season-ending ankle dislocation for starting WR Tyquan Thornton. That leaves the receiver room thin heading into a prime-time game.

Xavier Worthy and Jaylen Royals will also be involved. They were the only two receivers to out-snap Armstrong in Week 6’s game against Los Angeles. Expect that trio to handle the bulk of the work on Sunday.

What it means for Justin Watson and the practice squad

I don’t expect WR Justin Watson to be called up this week. The Chiefs need a running back after Brashard Smith suffered a hamstring injury late in the practice week. Chiefs head coach Andy Reid said RB Jayden Ott would be elevated to replace Smith.

Watson could still be called up. It depends on what happens at linebacker with Cooper McDonald, who is listed as questionable for Sunday’s game. McDonald was designated to return to practice after landing on injured reserve with a knee injury. He has missed the past four weeks of the 2026 NFL season.

If McDonald isn’t ready, Kansas City will have some roster math to work through before kickoff. Watson’s status could hinge on how the team fills that gap.

A tough test against the Seattle secondary

As for Armstrong, Week 7’s game against Seattle is an opportunity to keep proving the Chiefs right about his abilities. It won’t be easy. The Seahawks allow the fewest total yards to opposing pass catchers per game in the 2026 NFL season.

This is about as difficult a matchup as a young receiver can draw in his first week on the active roster. Still, Armstrong has already shown he can contribute without the ball, and that should keep him on the field regardless of how the targets shake out.

If Armstrong can flash and make plays against this secondary, the proof will be in the pudding. He’s exactly where he should be.
