KANSAS CITY, Mo. — Steelers coach Mike Tomlin called Chiefs tight end Travis Kelce the “best in the business.”

He talked about how wide receiver Tyreek Hill can create “unbelievable issues.”

He waxed poetic about defensive tackle Chris Jones and his rare “ability to disrupt an overall offensive game.”

Well, there’s a chance Tomlin won’t see any of them Sunday.

The three perennial Pro Bowl picks were part of a COVID-19 outbreak in Kansas City that snagged 13 players on the active roster and three more on the practice squad. And while there’s a chance that all three test out of protocol in time to suit up for a crucial showdown Sunday, there’s also a chance that they’ll be watching on television.

“We’ve got a big week ahead of us,” Tomlin insisted. “We’ve got some big days ahead of us, and we look forward to heading to Kansas City and putting our skills on display against a group that’s an AFC titan.”

Indeed, it’s a big game for both teams Sunday.

The Steelers (7-6-1) kept their playoff hopes alive with last week’s offensively challenged 19-13 win over Tennessee, but their tie earlier this season leaves them staring up at eight-win Cincinnati and Baltimore in a crowded AFC North.

As for the Chiefs (10-4), they’ve won seven straight games behind a vastly improved defense and an offense that appears to be shrugging off a midseason slump. They’re trying to hold off the rest of the conference for the No. 1 seed — and with it the lone playoff bye and homefield advantage — while clinching a sixth consecutive AFC West championship.

“The Steelers are a good team. They do a lot of good things offensively and defensively,” Chiefs coach Andy Reid said. “You saw what they did last week with Tennessee. We have to cover everything and then we have to make sure we do what our guys do best, and get out and play.

“That’s how we roll.”

Along with Kelce and Hill, the Chiefs could be without right tackle Lucas Niang and backup tight end Blake Bell due to virus protocols. On defense, leading tackler Nick Bolton tested positive with cornerbacks Charvarius Ward and Rashad Fenton.

None of that seems to have the Chiefs worried, though. They dealt with a slew of injuries last season to reach their second consecutive Super Bowl, so they take to heart the next-man-up cliché that coaches push on anyone that will listen.

Besides, there’s still a chance that some of those players will be available for Kansas City by kickoff.

“We haven’t really changed much,” Chiefs quarterback Patrick Mahomes said. “There’s obviously some routes and things that Travis and Tyreek can run that no one in this world can, but we have a game plan that we put together that trusts these guys to make things happen. I’m going to keep trusting them.

“And hopefully we have Travis and Tyreek back, but if not, we’ll be ready to go.”

The Steelers put starter Devin Bush and fellow linebacker Marcus Allen on the COVID-19 list along with offensive tackle Zach Banner. Robert Spillane and rookie Buddy Johnson are first in line to get the additional reps at linebacker, while Joe Haeg would be the primary backup offensive tackle.

The Steelers traded defensive end Melvin Ingram to the Chiefs last month for a sixth-round draft pick.
