Flacco (illness) was placed on the reserve/COVID-19 list Thursday, Rich Cimini of ESPN reports.
Flacco is unvaccinated and will thus have to miss a minimum of 10 days, which means he could return just before the Jets face the Buccaneers in Week 17, but he definitely won't be available Sunday against the Jaguars. Josh Johnson's now a member of the Ravens, but the Jets still have Mike White on hand to back up Zach Wilson while Flacco's unavailable.
