What happened: The fourth Hard Knocks installment reduced Seattle’s move to finalize Arnold’s contract to a passing reference tied to his workout and the decision to sign Trevon Diggs. Seattle initially expected Arnold to practice and play during the preseason.

Why it matters: Arnold would enter the commissioner’s exempt list upon signing, leaving him ineligible to practice or play while receiving pay that counts against the salary cap. He faces eight felony charges stemming from an alleged robbery and kidnapping scheme and maintains his innocence.

What to watch: Watch whether Seattle completes the agreement after the preseason and how the NFL handles Arnold’s roster status.
