News: Parmele, not Stepfan Taylor, will replace Jonathan Dwyer as Arizona's short-yardage back.
Impact: Parmele was out of football last year and has yet to run for an NFL touchdown, so he seems like an odd fit for a short-yardage/goal-line role. Still, the Cardinals will evidently give him the first shot at replacing Dwyer. Perhaps Taylor will get his chance if Parmele proves ineffective.
News: Ellington (foot) is probable for Sunday's game against San Francisco.
Impact: A matchup with the 49ers in a Drew Stanton-led offense aren't ideal circumstances for Ellington, but the big-play back is ready to give it his best shot. Ellington is running strong through his foot injury, totaling 144 yards on 28 carries (5.1 YPC) and catching six passes for 37 yards.
News: Palmer (shoulder) won't start Sunday's game against San Francisco, but is listed as questionable.
Impact: The 'questionable' designation seems insincere, as Palmer definitely won't start the game and is fully expected to sit in its entirety. Palmer's absence hurts Michael Floyd and Larry Fitzgerald to a fairly significant extent.
News: Stanton will start against San Francisco on Sunday.
Impact: Stanton wasn't good against the Giants last week, completing 14-of-29 passes for just 167 yards, taking four sacks. The 49ers defense has been mostly effective this year, so it's hard to see Stanton getting much going against them. Owners of Michael Floyd and Larry Fitzgerald should cross their fingers for an imminent Carson Palmer return, but it's not clear when to expect Palmer to return from his shoulder injury.
News: The Cardinals have placed Abraham (concussion) on IR, the team's official site reports.
Impact: The report notes with the linebacker's contract set to expire after this season, Abraham has probably played his last game for the Cardinals. Abraham's roster spot was filled by the team's addition of punter Drew Butler.
News: Arizona has placed 15-year veteran John Abraham on injured reserve, ending his season with the Cardinals. The 36-year-old outside linebacker sustained a concussion in the season opener against San Diego. He left the team briefly after that, reportedly contemplating retirement, before making an attempt to return this week. He had not been able to practice, however.
Impact: Abraham is the NFL's active career sacks leader with 133 1/2, ranking him ninth on the league's all-time list. He had 11 1/2 sacks with the Cardinals last season and is in the second year of a two-year contract with Arizona.
News: Stanton will start at quarterback when the Cardinals play the San Francisco 49ers on Sunday. Arizona coach Bruce Arians says that if Carson Palmer is in good enough condition, he will be the backup quarterback. But Arians says Palmer, out with a nerve problem in his shoulder, still is unable to throw a pass.
Impact: Stanton was the quarterback in Arizona's 25-14 road win over the New York Giants last Sunday. It was the first time he had played in a regular-season game in four years. After this week, Palmer will have some time to heal because the Cardinals have a bye next week. Rookie Logan Thomas will be the backup if Palmer can't fill that role.
News: Arizona coach Bruce Arians says that if Carson Palmer is in good enough condition, he will be the backup quarterback when the Cardinals play the San Francisco 49ers on Sunday. Drew Stanton is slated to start for the second straight game.
Impact: Arians says Palmer, out with a nerve problem in his shoulder, still is unable to throw a pass. After this week, Palmer will have some time to heal because the Cardinals have a bye next week.
