The Chiefs had a staffer recently test positive for COVID-19 and may be observing some fallout. They placed Chris Jones on the reserve/COVID-19 list Thursday.

Jones will be forced to isolate for five days and, unless his close contact with the person who tested positive came before Wednesday, will miss the Chiefs’ Week 9 game against the Panthers.

Chiefs VP of Sports Medicine and Performance Rick Burkholder tested positive for the coronavirus, Tom Pelissero of NFL.com tweets. With Burkholder serving as a Chiefs trainer, it is possible the team will place more players on its COVID-19 list ahead of Week 9.

Jones has not tested positive, per Mike Garafolo of NFL.com (on Twitter), but instead profiles as a close contact. This close contact may well have been separate from Burkholder’s positive test, with Albert Breer of SI.com tweeting Jones’ encounter with a COVID-positive person occurred outside the Chiefs’ facility.

The Chiefs gave Jones a four-year, $80MM extension this summer. The NFL’s record holder for consecutive games with a sack, Jones has anchored Kansas City’s defensive line for years. The fifth-year defensive tackle has 4.5 sacks this season.
