What's confirmed. Knight (concussion) is out for Week 9. He left the Cardinals' Week 8 game and was ruled out in-game at the time. Friday's injury report makes the next-week status official rather than leaving owners guessing through the weekend.
How we got here. Knight suffered the concussion during Week 8 play. RSO covered that in-game exit alongside other Cardinals and Cowboys outs. He did not clear protocol in time for this week's game. Concussion returns are stepwise, so a Friday out tag is the expected outcome when a player has not practiced fully through the week.
Who gets the work. Arizona's backfield without Knight shifts to the healthy backs already on the roster for Week 9. With Jacoby Brissett headed to Baltimore in the trade news that dominated the Cardinals' week, the offense is in flux on both sides of the ball. Check Friday's full Cardinals injury report for which back took first-team reps. Prefer the rusher already getting early-down and passing-down work over a speculative handcuff claim unless your league is deep.
What RSO owners should do now. Sit Knight for Week 9. Keep him rostered in dynasty and contract leagues through the protocol window unless you need the spot for a clear upgrade. Do not stash a low-upside Arizona handcuff solely because Knight is out unless that back already has a defined role on the Friday report.
What to watch next. Next week's practice participation and any protocol clearance note from Arizona. The first full practice without limits is the signal he is nearing a return, not a single limited session.
