Emari Demercado

Demercado could regain his No. 2 role behind fill-in starting RB Bam Knight if he can play this weekend. Unfortunately, his potential return comes against the Rams' top-tier defense. Demercado may be able to catch a few passes in a trailing game script, but it is tough to view him as a player with much of a ceiling.

Demercado (ankle) was a limited practice participant Thursday, Josh Weinfuss of ESPN.com reports.

Cardinals RB Trey Benson (knee) did not practice on Wednesday. He was limited last Wednesday before missing the final two practices of the week, so it sure looks like he suffered a setback. Don't bank on Benson playing vs. the Rams this weekend. His absence would again leave Bam Knight as Arizona's lead back, with Michael Carter and potentially Emari Demercado, who was limited on Wednesday, handling passing downs.

Demercado (ankle) practiced on a limited basis Wednesday, Zach Gershman of the Cardinals' official site reports.

Head coach Jonathan Gannon was noncommittal when asked about Benson's status. The young back appeared to be nearing a return from injured reserve last week, but he was downgraded to a DNP on Thursday and was ruled out the following day after another missed practice. It's possible he suffered a setback during practice. Needless to say, it doesn't look like he will be back in the lineup this week. Emari Demercado was back at practice today, giving him a shot to suit up on Sunday after missing last week's game with an ankle injury.
