Brown (hamstring) didn't take part in Wednesday's practice, Darren Urban of the Cardinals' official site reports.
After struggling through a hamstring injury for the past few weeks, Brown was able to handle a healthy share of the offensive snaps (53 of 61) in Sunday's win, during which he recorded his first catch since Week 7 in a 43-yard, one-touchdown performance against the Bengals. Wednesday's absence may just be a precautionary measure, but his progress as the week unfolds will reveal whether owners should begin to worry about his Week 12 availability.
Cardinals defensive end Calais Campbell was a one-man wrecking crew Sunday against the Rams, racking up 11 tackles (10 solo), three tackles for loss, two quarterback hits, and 0.5 sacks.
Campbell was everywhere in Week 4, but the Cardinals' defense itself was unable to force a turnover, after accumulating seven (all interceptions) over the course of the first three weeks of the season. Stuck in the 50-to-75 tackle territory in each of the past five campaigns, he currently has 25 to his credit, which is a career-best pace. On the other side of the coin, the half sack Sunday was his first in the category in 2015, so he has some work to do to uphold his standard (6-to-9 sacks in six consecutive seasons).
Fitzgerald (ankle) was a limited practice participant Wednesday, Darren Urban of the Cardinals' official site reports.
If Fitzgerald replicates last week's practice schedule, he'll follow Wednesday's cap in reps with a full showing Thursday, which will pave the way for active status in Week 12 at San Francisco. With a 90-yard effort this past Sunday against the Bengals, he's reached that threshold in six of 10 games this season and will look to do it again against a 49ers pass defense that ranks 27th in the NFL.
Floyd (hamstring) was limited in practice Wednesday, Darren Urban of the Cardinals' official site reports.
The appearance at practice marks Floyd's first since sustaining a hamstring injury in Week 10. While an uninhibited showing before week's end would clear up any doubt about his odds of suiting up Sunday at San Francisco, the Cardinals are more apt to make him a game-time call. In particular, head coach Bruce Arians mentioned Monday that Floyd must "open up and go" in order to play in Week 12.
Johnson (knee) was limited at Wednesday's practice, Darren Urban of the Cardinals' official site reports.
Johnson is tending to a knee injury at the moment, and his YPC in a given game has topped out at 3.63 over the last three contests (and four of the past five). Still, he's averaged 21 carries per outing during that stretch, meaning capped reps in practice could be strategic in order to get him in a better state of health. Nonetheless, interested parties should watch his activity level as the week continues to learn if he'll be hindered Sunday at San Francisco.
Peterson (ankle) didn't practice Wednesday, Darren Urban of the Cardinals' official site reports.
Clearly hobbled after Sunday's victory against the Bengals, Peterson's ankle injury is of keen interest, as the Cardinals may have to do without perhaps the NFL's top-performing cornerback for a period of time. On the other hand, there is a chance that he'll be able to practice by the end of the week, which would do wonders for his potential to suit up in Week 12 at San Francisco. If the training staff decides to rest Peterson, Justin Bethel will step into the base defense at cornerback opposite Jerraud Powers.
Boldin (hamstring) hauled in five of seven targets for 93 yards in Sunday's 29-13 loss at Seattle.
It was a brutal matchup for Boldin and he didn't appear to be 100 percent, looking gimpy on some routes. He also spent a little time on the bench in the first half, while the 49ers had the ball, warming up his tender hamstring. However, he made a number of tough grabs in traffic, and seemed to have a solid rapport with Blaine Gabbert, who did a nice job in the loss, completing 22 of 34 passes for 264 yards and a touchdown. Assuming Boldin made it out of Sunday's game without any setback, he'll have another tough matchup in Week 12 against the Cardinals.
Bowman (shoulder) had a relatively quiet game by his standards, recording nine tackles (four solo) in the 29-13 loss to the Seahawks.
Bowman continues to pop up on the injury report for a minor shoulder injury, but it didn't seem to affect the veteran linebacker as he was on the field for all 78 of the team's defensive snaps. With the opposition running the ball 44 times, you would think Bowman would have notched more than nine tackles, but Thomas Rawls was getting into the secondary consistently which did not benefit Bowman. A matchup against the Cardinals' potent air attack looms next week, so the tackle totals could be held in check for Bowman yet again.
Brooks (personal) returned to the field Thursday, recording five tackles (two solo) and a pair of sacks in the loss to Seattle.
Brooks had missed last week's contest to attend the funeral of his sister. He returned Thursday and the extra rest seemed to have given the veteran linebacker a boost. While this was a monster game, it has to be taken with a grain of salt, as the Seattle offensive line is, well, offensive.
Hyde (foot) won't participate in Wednesday's practice, Cam Inman of the San Jose Mercury News reports.
With each passing week and no practice participation, there's no telling when Hyde may be able to return from the stress fracture in his left foot. The sinking 49ers also have little reason to trot him out there until he's completely healthy, which will keep Shaun Draughn at the top of the RB pecking order. In back-to-back starts, Draughn has managed 28 carries for 95 yards and 12 receptions (on 16 targets) for 78 yards.
Antoine Bethea is set to start for the 49ers this season at strong safety with Eric Reid entrenched at free safety. But the former doesn't know who their secondary mates will be and he's expecting quite a battle.
Tartt finished with eight tackles (four solo) in Sunday's loss to Seattle.
Tartt has been starting at strong safety ever since Antoine Bethea (shoulder) was shut down for the season. He has been averaging 6.0 tackles in the those three starts. He doesn't seem like the type of player that will haul in too many interceptions, but his size and athleticism give him a little upside in IDP leagues for tackles, forced fumbles, and the occasional sack.
Smelter (knee) is slated to practice this week, the San Jose Mercury News reports.
Smelter will remain on the 49ers' Reserve/Non-Football Injury list for now, as the team has a three-week window in which to evaluate whether or not to officially add the wideout to the team's 53-man active roster.
