Hairston’s Bills debut is delayed by a knee sprain, placing him on short-term IR and pushing his season start to Week 5 versus New England. Buffalo leans on Tre’Davious White and Christian Benford in the interim, with Jordan Poyer on the practice squad to aid a secondary dealing with injuries. Mitch Trubisky remains the reliable backup as Will Howard and Caleb Ransaw land IR stints for Steelers and Jaguars. In a 17-game season, four missed games isn’t fatal, opening the door for a rapid rookie adjustment and future fantasy upside.
