Brown didn't practice Wednesday due to a foot injury, Tyler Drake of ArizonaSports.com reports.
Brown showed up on the Cardinals' Week 4 injury report Friday and was listed as a limited participant due to rest/foot. He was able to play Sunday at Carolina and earned a typical 94 percent of the offensive snaps on his way to six catches (on 11 targets) for 88 yards and one touchdown. However, Brown now isn't practicing at all to begin Week 5 prep, so his status bears watching as the weekend approaches to get a sense of his availability for Sunday's game versus the Eagles.
