Per Macdonald, Darnold also suffered a rib injury early in the team’s Week 8 loss to the Bears, though that doesn’t appear to be the reason he’s out this week. The fact that the Seahawks ruled him out ahead of their first practice report of the week was even released suggests this might be a multi-week injury. Drew Lock will draw the start versus Arizona. With two successful starts under his belt this year, Lock is a somewhat safe QB2 bet for Superflex managers.
