Brown returned to a full practice Friday, after logging limited sessions Wednesday and Thursday. He's played a clear second fiddle to Larry Fitzgerald so far, but Brown at least doesn't seem to be in much danger of losing the No. 2 role to Michael Floyd. Furthermore, the general perception of the gap between Fitzgerald and Brown is likely wider than the reality.
Ellington was limited throughout the week of practice, and while it won't be surprising if the third-year back suits up, head coach Bruce Arians said Chris Johnson will get the start. It thus seems Ellington will mostly be limited to passing-down work, if he does in fact play.
Between the late (4:25 PM ET) kickoff and limited role, Ellington doesn't hold much Week 4 appeal. His season-long value also appears to be in danger, as Johnson may hold on to the starting job.
Okafor logged full practices Thursday and Friday, setting him up for his normal workload in Sunday's game against the Rams. St. Louis has only surrendered five sacks this season, but Nick Foles has only attempted 87 passes.
Rams wideout Kenny Britt (shoulder) returned to practice Friday and is listed as probable for the Week 4 battle against the host Cardinals.
His ailment isn't much of a concern, even though he missed practice Tuesday and Wednesday. He has emerged as the closest thing the Rams have to a No. 1 wide receiver, leading his position group in targets (17), catches (11) and snaps (130) through three games.
Cunningham was a late addition to the injury report for Friday, with a minor knee issue holding him out of practice. He's still expected to play, albeit in a limited role now that Todd Gurley and Tre Mason are both healthy. Cunningham won't see much work outside of obvious passing situations.
