Knight will need to clear protocol if he hopes to suit up in time to play in Week 9 against the Seahawks. The former UDFA has turned in a solid season thus far for the Cardinals, rushing for 28-168-0 while adding another six receptions for 43 additional yards. With Jeremiyah Love (ankle) likely to miss time, Knight could again find himself in a split with Tyler Allgeier when he returns. The Cardinals will likely need to address their running back room at some point in the week with Allgeier currently being the only healthy back on the roster.
