Darnold wasn't practicing Wednesday due to an apparent foot injury, Connor Hughes of The Athletic reports.
Darnold -- who came up limping after taking a sack in Sunday's loss to Miami -- was sporting a walking boot on his right foot on the sideline during the Jets' first practice of Week 10. Per Rich Cimini of ESPN.com, Darnold admitted Monday that he was "dinged up," but the quarterback suggested that it wasn't anything serious. Now that he's absent from practice, Darnold's status for this weekend's game against the Bills must now be monitored. Veteran Josh McCown would be in line for the start if Darnold can't go.
