New England Patriots center James Ferentz was placed on the reserve/COVID-19 list on Friday.
It appears that Ferentz was the positive test that emerged on Friday, causing the Patriots to cancel practice. Ferentz played 76 snaps at center in Week 4's loss to the Kansas City Chiefs.
The Patriots are 9.0-point favorites over the Denver Broncos in Week 6.
