Cardinals RB Trey Benson (knee) has been designated to return from IR. That means he'll practice this week, although it's still unclear if Benson will play vs. the Jaguars this weekend. HC Johnathan Gannon said Wednesday that Benson will be evaluated "day by day" this week. We'll keep you updated on his status. Benson should take over as Arizona's lead back once he's cleared to play. RB Emari Demercado (ankle) has been ruled out for Week 12.

Cardinals RB Emari Demercado suffered a high-ankle sprain in the Week 11 loss to the 49ers and will "likely" miss Sunday's game vs. the Jaguars, according to ESPN's Adam Schefter. Demercado will probably miss more time beyond that and can be dropped from fantasy rosters. RB Michael Carter stepped into Demercado's change-of-pace, pass-catching role vs. San Francisco last week, with RB Zonovan Knight handling most of the early-down work. Expect to see that arrangement against Jacksonville, assuming RB Trey Benson remains out.

Cardinals RB Bam Knight (ankle) is active for today’s game vs. the 49ers. We’re expecting him to lead the backfield in carries, but RB Emari Demercado is a threat to steal work. Avoid this backfield in fantasy lineups if possible.

Cardinals RB Bam Knight (ankle) is expected to play vs. the 49ers today, according to ESPN's Adam Schefter. Knight got in three limited practices this week. We're projecting him to lead Arizona in carries today, but this has been a difficult backfield to peg since RBs James Conner and Trey Benson went down.

Cardinals RB Bam Knight (ankle) was limited in practice all week and is listed as questionable for Sunday’s game vs. the 49ers. We’re tentatively expecting Knight to play but will look for updates on his status. Knight remained ahead of Emari Demercado as Arizona’s lead back before going down last week.

Cardinals RB Bam Knight (ankle) got in a limited practice on Wednesday. He was operating as Arizona's lead back before exiting last week's game, but he mustered just 28 yards on 10 carries. This remains a backfield to try to avoid until RB Trey Benson returns.

RB Emari Demercado led the Cardinals in rushing yards for the second straight week in Sunday's loss to Seattle. But nearly all of his ground production came on a single 55-yard run early in the fourth quarter of the blowout defeat. Demercado logged just four total carries, trailing Bam Knight's team lead (10) and leading Michael Carter by just one. WR Greg Dortch scored the team's only rushing TD, from 4 yards out in the second quarter.

Cardinals RB Bam Knight suffered an ankle injury in the second half of Sunday's game vs. the Seahawks and is questionable to return. His absence leaves the backfield to Emari Demercado and Michael Carter.

The Cardinals plan on re-signing RB Michael Carter, according to ESPN's Josh Weinfuss. Carter was released on Monday, but it sounds like it was a procedural move. And that makes sense considering his departure leaves only Bam Knight and Emari Demercado (who missed Arizona's last game back in Week 7) in the RB room. We'll let you know if and when the Carter re-signing becomes official. Knight is still worth adding where available as the likely lead back for Monday night's game vs. the Cowboys' 31st-ranked RB defense. Carter, assuming he re-joins the team, will be on the RB3/Flex radar for that one.

The Cardinals released RB Michael Carter. He led the backfield just a few weeks ago but fell behind RB Bam Knight in Arizona's last two games. Carter's departure leaves Knight and Emari Demercado as the only healthy RBs on the Cardinals' active roster. We'll see if the team makes another move this week, but Knight now projects to control carries in a plus matchup vs. the Cowboys next Monday night. RB Trey Benson is eligible to return for Week 10.

In a surprising move, Jonathan Gannon announced before Arizona's Week 6 game in Indianapolis that Zonovan Knight, who was listed as third on the depth chart and was just activated from the practice squad in Week 5, would draw the backfield start for the Cardinals. The move paid off, as Knight led the team in rushing and scored a 1-yard TD in the first quarter in Arizona's 31-27 loss.

Cardinals RB Emari Demercado is questionable to return to Sunday's game vs. the Colts with an ankle injury. His absence leaves the backfield to Michael Carter and Bam Knight. We'll update Demercado's status when we know more.

ESPN's Adam Schefter reports that Cardinals RB Zonovan "Bam" Knight will play a "more prominent role" ahead of Michael Carter today against the Colts.

Michael Carter led the Cardinals backfield Sunday in the first game since RB Trey Benson went down with a knee injury. Carter handled 18 of the 25 RB rushes in the Week 5 loss to the Titans. He also drew five of the team's six RB targets, tying Marvin Harrison Jr. for second on the team in that category. Carter caught all five of those to match TE Trey McBride for the team reception lead. But his yardage efficiency in both phases failed to impress.

Emari Demercado generated the most rushing yards Sunday in a Cardinals backfield spreading the work around after losing both James Conner and Trey Benson to knee injuries. But Demercado overshadowed the work split and his performance and effectively lost his team the game by voluntarily dropping the ball before he crossed the goal line on what should have been a long fourth-quarter TD run.

The Cardinals "plan to ride the hot hand" in the backfield vs. the Titans on Sunday, according to ESPN's Jeremy Fowler. "That includes Michael Carter and Bam Knight on base downs and Emari Demercado on third downs," Fowler adds. We still expect Carter to get the first shot at developing that hot hand -- and he remains the best fantasy bet in this backfield. But he clearly carries a wide range of outcomes. Demercado seems unlikely to get big rushing volume but could dominate passing-down work. Knight could be worth stashing in super deep fantasy leagues while we wait to see what this backfield looks like, but he shouldn't be in Week 5 fantasy lineups.
