The placements of Robinson and Kilgore on the COVID-19 list mark the first coronavirus-related issues ahead of Sunday's Super Bowl at Raymond James Stadium in Tampa, Fla. Both players were added to the list due to close contact.
As close contacts, Robinson and Kilgore could potentially still play in Super Bowl LV against the Tampa Bay Buccaneers if they have five straight days of negative tests.
"The NFL has done a great job with it, presenting different safety things for the players to stay as safe as possible," Chiefs head coach Andy Reid told reporters Monday. "We've been hammering this point home forever.
"The problem is you're fighting the invisible man. It just gets you when least expected, and we're seeing that in everything. It's an unfortunate thing."
The 26-year-old Robinson recorded a career-best 45 receptions for 466 yards and three touchdowns this season.
Kilgore, 33, appeared in seven games, including four starts, in the 2020-21 season. The veteran offensive lineman is listed as the Chiefs' backup center behind Austin Reiter.
"These guys were being as safe as they could be, and we'll just see how it goes," Reid said. "But the league has built-in rules and regulations, so we follow those, and it'll all work out. It'll all work out for them when it's all said and done."
The Chiefs and Buccaneers are set to play at 6:30 p.m. EST Sunday in Tampa.
