Darnold (shoulder) has been ruled out for Sunday's game against the Cardinals.
As a result, Joe Flacco will start at quarterback for the Jets in Week 5, and possibly longer, given that head coach Adam Gase said Darnold is in "a lot of pain" as a result of his AC joint sprain, according to Rich Cimini of ESPN.com. Beyond Sunday, Darnold is viewed by the Jets as week-to-week, which clouds his status for the team's Week 6 contest Oct. 18 versus the Chargers.
