Melton (toe) is listed as questionable for Sunday's game versus San Francisco, Darren Urban of the Cardinals' official site reports.
Melton didn't practice Wednesday and was limited Thursday and Friday. He's now considered questionable for the Week 3 meeting with the 49ers. Garrett Williams (Achilles) doesn't hold an injury designation, so his availability will help lessen the blow if Melton can't get on the field.
