Palmer (concussion) has been cleared to return to practice Wednesday, NFL Network's James Palmer reports.

EDGE Analysis

Palmer seems to have passed through concussion protocol Tuesday, as anticipated by head coach Bruce Arians. The veteran quarterback seemingly has a shot to log full practices throughout the week, with only a setback capable of preventing him from starting Sunday's game against the Jets. Coming off an ugly showing in Pittsburgh, the Gang Green defense is allowing an NFL-worst 9.2 yards per pass attempt, along with a 12:2 touchdown:interception ratio.

Palmer is anticipated by coach Bruce Arians to clear concussion protocol Tuesday, Kent Somers of AZCentral.com reports.

EDGE Analysis

Palmer has been subject to the league's concussion protocol since being knocked out of last Sunday's game against the Rams, and although that resulted in him missing Thursday's win in San Francisco, the veteran could get the green light to return Tuesday. That would allow Palmer a full week of practice ahead of next Monday night's Week 6 contest versus the Jets, which would obviously be a good development for the Cardinals and fantasy owners alike.

Palmer (concussion) is "feeling great by all indications", according to general manager Steve Keim, Cardinals writer Darren Urban reports.

EDGE Analysis

Palmer remains in the final stages of the league's concussion protocol, but appears to be approaching his clearance by the sounds of recent reports. After missing Thursday's win over the 49ers, Palmer doesn't have to be ready to play until next Monday, when the Cardinals host the Jets. That added time seems to bode in Palmer's favor, but until he indeed passes protocol, Drew Stanton should be considered Arizona's starter at quarterback.

Head coach Bruce Arians said Friday that Palmer is in the final phases of the concussion protocol, the Cardinals' official site reports.

EDGE Analysis

On a short week, Palmer was hard-pressed to complete every portion of the protocol and suit up Thursday at San Francisco. Although he didn't make the trip, he lifted weights Friday, according to Arians, but he's unsure whether Palmer will be able to play in Week 6 against the Jets. With a Monday night contest on tap, the Cardinals don't have to release an injury report until Thursday, but another absence from Palmer would place Drew Stanton under center.

Palmer (concussion) has been ruled out for Thursday's game in San Francisco, Kent Somers of the Arizona Republic reports.

EDGE Analysis

The development isn't a surprising one with a concussion in tow and only three days between contests. Palmer will thus hand off quarterback duties to Drew Stanton for this divisional matchup against the 49ers. Meanwhile, Zac Dysert will serve as Stanton's backup.

Although Palmer (concussion) didn't practice either Monday or Tuesday, Ed Werder of ESPN reported that the quarterback is "fully integrated in prep" for Thursday's game at San Francisco.

EDGE Analysis

Werder's comment relating to preparations could merely mean that Palmer has joined forces with head coach Bruce Arians to get his replacement Drew Stanton up to speed with the 49ers. Palmer's own activity level depends on his standing in the league's protocol for head injuries, but he was yet to be given clearance for even individual drills at this time. One practice remains to make inroads toward potential active status Thursday, after which he'll be denoted either questionable, doubtful, or out for Week 5.

Head coach Bruce Arians said Palmer (concussion) looked good Tuesday morning and still has a shot to play in Thursday's game against San Francisco, Matt Barrows of the Sacramento Bee reports.

EDGE Analysis

While the Cardinals obviously aren't ruling him out, Palmer still faces an uphill battle to get ready for Week 5, needing to clear the NFL's concussion protocol within four days of suffering the brain injury. Such a recovery isn't unheard of, but it also isn't the norm. Drew Stanton is the most likely starter for Thursday's game in San Francisco.

Palmer, who is currently subject to the league's concussion protocol, seems unlikely to play Thursday against the 49ers, NFL.com's Ian Rapoport reports.

EDGE Analysis

Palmer was knocked out during the fourth quarter of Sunday's loss to the Rams, resulting in backup Drew Stanton finishing the game at quarterback. With only a few days before the Cardinals' Week 5 contest, Palmer always faced a quick turnaround to play, but it seems doubtful he'll be able to do so now that he also has a concussion to overcome. Following this Thursday's game, Arizona doesn't play again until Oct. 17, essentially giving Palmer two weeks to be cleared if he indeed misses this week's NFC West tilt.

Palmer left Sunday's outing against the Rams to be evaluated for a concussion, Josh Weinfuss of ESPN.com reports.

EDGE Analysis

The back of Palmer's head took a hard hit from the turf on a fourth-quarter sack, and he was clearly woozy in the aftermath. Following a punt, the Rams proceeded to go up 17-13, so Drew Stanton is the man under center as the Cardinals attempt a game-winning drive. If Palmer is diagnosed with a concussion, his practice participation will be monitored closely in the coming days.

Palmer was dreadful in Sunday's 33-18 loss at Buffalo, completing 26 of 50 passes for 261 yards and four interceptions.

EDGE Analysis

The Cardinals went three-and-out on each of their first five possessions, a span in which Palmer went two of 10 for eight yards and suffered the first of five sacks. By the time he engineered the team's initial first down, the deficit had grown to 17-0, but a David Johnson touchdown run with 1:05 remaining before halftime put the visitors in position for a comeback. Arizona was unable to parlay the second-half kickoff into more than another punt, though, and Tyrod Taylor soon culminated the Bills' ensuing drive with a 20-yard touchdown. Palmer again drove the Cards into field-goal range, only to stall out at Buffalo's 10-yard line, and a snap over the holder's head was hunted down by Aaron Williams, who scooped up the snafu and dashed 53 yards to the end zone to put a stranglehold on the contest. Although Palmer achieved a semblance of consistency with a touchdown and field goal on the next two possessions, he was clearly pressing the issue thereafter, ending the final four drives with interceptions (or his first turnovers of the season). He'll look to turn it around next Sunday against the Rams at University of Phoenix Stadium.
