Drew Stanton QB ARI 2 Days

Stanton (knee) is doubtful for Sunday's game against Seattle.

Stanton was able to make a limited practice appearance Thursday, but he sat out altogether Friday. Ryan Lindley will start in what's presumably an impending trainwreck for the Arizona offense.

Stanton (knee) was limited in Thursday's practice, the Cardinals' official site reports.

The news is shocking to say the least, especially after Stanton was seen working on the side during the open portion of practice Thursday. While the Cardinals said earlier in the week that Stanton should be healthy enough to play in a game in "about four weeks," his earlier than expected return to drills doesn't imply that game action is imminent. However, the situation has suddenly become murkier than expected, meaning his status should be monitored closely in the coming days. In any case, Ryan Lindley remains in line to start Sunday against the Seahawks, and Thursday's development seems hard-pressed to change that sentiment.

Stanton (knee) may be able to return in "about four weeks," ESPN.com reports.

A range of return dates have been mentioned since Stanton suffered a partial tear of the ACL and a sprained MCL in his right knee during Thursday's win at St. Louis, but in order to heal properly, four weeks appears to be a more realistic timeframe. Consider him "week-to-week" for now, with an appearance in the postseason much more attainable, if the Cardinals secure a first-round bye. In the meantime, Ryan Lindley, who took over for Stanton, is on track to start next Sunday against the Seahawks, though coach Bruce Arians has yet to commit to either of his healthy options (Lindley or rookie Logan Thomas).

Head coach Bruce Arians said Friday that he definitely thinks Stanton (knee) can return this season, but he would be surprised if the quarterback is able to play next week against Seattle.

Stanton is currently on crutches, and a sprained knee is a difficult thing to return from after just one week, even if he does have a few extra days due to this week's Thursday game. Arians added that he has not yet made a decision on whether Ryan Lindley or Logan Thomas would start against Seattle if Stanton is unable to play. Next week's practices should go a long way toward determining what the Cardinals' Week 15 quarterback picture will look like.

An MRI confirmed that Stanton has a sprained knee and is week-to-week, NFL.com's Ian Rapoport reports.

The Cardinals do not believe Stanton's season is over, and the quarterback said he experienced "huge relief" when learning the results of the MRI. However, Stanton still faces an uphill climb to be ready to play Week 16 against Seattle, so it's very possible that either Ryan Lindley or Logan Thomas is forced to start against the Seahawks.

Mike Jurecki of Fox Sports 910 indicates that he is hearing that Stanton suffered a sprained ACL and Grade 2 MCL sprain in Thursday's win over the Rams.

We'll await confirmation of the report, but Stanton's status for Week 16's game against Seattle on Dec. 21 is clearly dicey, with the Cardinals now down to Ryan Lindley (who took over for Stanton on Thursday) and Logan Thomas as healthy QB options, with Carson Palmer on IR.

Speaking after Thursday's game, Cardinals head coach Bruce Arians said Stanton (knee) had already been dealing with an injury in his right knee, prior to exiting Thursday's contest. Arians added that Stanton will undergo an MRI.

The need for an MRI comes as no surprise, and while Stanton's ankle was thought to be the greater concern, he was listed with both ankle and knee issues on the Week 15 injury report. Stanton exited Thursday's game after a third-quarter sack, giving way to Ryan Lindley, who is listed third on the depth chart. Lindley didn't play well in limited action, and the Cardinals might consider going with Logan Thomas for Week 16 against the Seahawks, if Stanton is unable to play. Stanton appeared to be dealing with significant pain, but there's no need for a rash reaction, as the Cardinals will likely have an update by the end of this weekend.

Cardinals head coach Bruce Arians said after Thursday's game that he does not have any idea about the extent of Stanton's right knee injury, NFL Network on twitter reports.

Stanton will presumably undergo an MRI, after exiting Thursday's game in the third quarter. He appeared to be in significant pain, and had trouble putting any weight on his right leg. Ryan Lindley, who handled the final 20-plus minutes, will likely start in Week 16 against the Seahawks, if Stanton is unable to play.

Stanton, who left Thursday's game in the third quarter with a right knee injury, will not return to the contest, Kent Somers of azcentral.com reports.

The news comes as no surprise, given that Stanton appeared to be in a considerable amount of pain. Ryan Lindley is in at quarterback, and he will likely start next week's game against the Seahawks, if Stanton is unable to play.

Stanton left Thursday's game against the Rams with a right knee injury, and he is questionable to return, Kent Somers of azcentral.com reports.

Stanton entered the contest with a minor ankle concern but seemed fine through the game's first 36 minutes. He then took a hard hit on a sack, and was taken back to the locker room shortly thereafter. The Cardinals surprisingly went with Ryan Lindley instead of Logan Thomas, opting for experience over physical talent. If Stanton doesn't return, he'll finish 12-of-20 for 109 yards, with no touchdowns or interceptions.
