Jacksonville placed Chaisson on the reserve/COVID-19 list Monday after he tested positive for the virus, Tom Pelissero of NFL Network reports.
Chaisson played a season-high 53 percent of the defensive snaps Sunday versus the Jets, but he's now sidelined on the COVID list. Fellow outside linebackers Josh Allen (illness), Lerentee McCray (illness) and Jordan Smith (illness) are also following the NFL's COVID-19 protocols.
