Chiefs lose Kelce to COVID-19 protocols for Pittsburgh Steelers clash
Kelce - missing his first game of the season - is joined by Nick Bolton, Lucas Niang, Harrison Butker and Tommy Townsend in being ruled out, while coaches Mike Kafka, Greg Lewis and Corey Matthaei are also under coronavirus protocols.
The tight end had been pre-emptively activated in the hope that he would be cleared to play, but he must now sit the match out as the Chiefs chase the AFC West title - which they would clinch with victory over the Steelers if the Los Angeles Chargers also fail to win - without him.
The Chiefs will feel Kelce's absence particularly keenly after his career-best performance in the 34-28 victory over the Chargers last time out, catching 10 passes for 191 yards and scoring the game-winning touchdown.
He is set to be replaced in the side by Blake Bell, who has just returned from the COVID list himself.
