Melifonwu (ankle) has been ruled out for Sunday's game against Arizona.
Melifonwu continues to nurse an ankle injury that has prevented him from taking the field so far this season. The safety didn't practice in any capacity this week, so it's unclear how close he may be to making a return. Melifonwu's next chance to make his season debut will come on Monday Night Football against Seattle on Sept. 30.
