Jones has been diagnosed with a "slight separation on [his] AC joint," which he sustained during Friday's preseason win against the Jets.
After injuring his left shoulder, Jones was forced from the contest, and while the ailment was initially deemed a sprain, the nature of the injury could knock him down a peg in the fantasy realm. On a positive note, head coach Jay Gruden stated that it "won't be too long" until Jones returns to practice, so he may bounce back sooner than expected.
