Rashad Johnson DB ARI 16 Mins

Johnson (knee) is probable for Sunday's game against Philadelphia.

Johnson is having the best IDP season of his career so far, totaling 36 tackles and two interceptions in six games, but he figures to see his opportunities lessened in the upcoming games as Tyrann Mathieu (knee) reaches full health and rookie first-round pick Deone Bucannon catches up to the speed of the NFL game.

Johnson is slated for an evaluation of his patellar tendon, but the Cardinals believe that the ailment is tendinitis, Mike Jurecki of FOX Sports 910 Phoenix reports.

The upcoming exam will ultimately determine Johnson's course of action through practice this week, but full practices are likely out of the question, especially Wednesday's iteration. His three solo tackles in Week 7 doubled as his least dynamic IDP line of the season, which may have been a consequence of playing through the aforementioned ailment.

Johnson tallied a team-high eight tackles (six solo), two picks, and one touchdown after interception during Sunday's win against Washington. In the end, he took the field for all 60 defensive snaps, FOX Sports 910 Phoenix reports.

Despite a significant increase in Tyrann Mathieu's snap count -- 49 versus 15 last Sunday -- Johnson continues to be a mainstay in the Cardinals' secondary, equaling starting corners Antonio Cromartie and Patrick Peterson by logging all snaps on defense. As the team's leading tackler with 33, Johnson's peripheral stats so far put him over the top as the No. 1 IDP of the bunch. Meanwhile, because Todd Bowles continues to use six defensive backs more often than not, there's no reason to believe Johnson can't keep up the torrid start to his sixth NFL campaign.

Johnson contributed six tackles (five solo) and one tackle for loss during Sunday's loss at Denver. Overall, he played 77-of-81 defensive snaps, FOX Sports 910 Phoenix reports.

Because the Cardinals' defense is banged up, coordinator Todd Bowles has had to rely on his secondary to shore up deficiencies elsewhere. Johnson has so far taken on far more snaps than Tyrann Mathieu (15), the No. 1 free safety on the depth chart, due to the latter's recovery from last December's knee ligament tears. Consequently, Johnson is the relevant IDP option among the duo until Mathieu displays an ability to play most downs.

Johnson took all 64 defensive snaps in Sunday's victory versus the 49ers, FOX Sports 910 Phoenix reports.

Ranking second on the team with eight tackles on the day, Johnson may be in for a reduction in workload following the Cardinals' Week 4 bye, as the free safety spot is ultimately intended for Tyrann Mathieu. Speaking of Mathieu, he tripled his snap count to 15, racking up an impressive six solo tackles in the process. Until the second-year pro is cleared for a full workload, Johnson is a viable DB option for those in IDP formats, but the clock is winding down on the latter's prospects.

Johnson (ankle) is active Sunday against the Giants at New York, Mark Dalton of the Cardinals' official site reports.

The return of Tyrann Mathieu (knee) to the Cardinals' defensive backfield is sure to eat into Johnson's snap count in Week 2, hindering his IDP potential.

Johnson (ankle) is probable for Sunday's game against the Giants.

Johnson is one of the more steady veterans on the Arizona roster, but his IDP appeal is limited since all of Tony Jefferson, Deone Bucannon and Tyrann Mathieu are battling for safety snaps.

Johnson (ankle) was a full participant in Thursday's practice, the Cardinals' official site reports.

Johnson began the week with limited reps Wednesday, but with an upgrade to full practice already, he appears poised to miss no time. Unfortunately, Tyrann Mathieu (knee) has been unhinged during drills this week and could make his first appearance since Dec. 8, which would likely push Johnson to a reserve role. Friday's injury report should ultimately reveal the state of the Cardinals' defensive backfield heading into Week 2 versus the Giants in New York.

The Cardinals' website projects Rashad Johnson as the team's Week 1 starter at free safety.

It's the latest sign Tyrann Mathieu (ACL/LCL surgery) won't be ready for Week 1. Coach Bruce Arians recently called October 1 his "target" date for Mathieu. Cardinals.com projects first-round pick Deone Bucannon to start at strong safety. Leaning on aging John Abraham (36) and Darnell Dockett (33) for pass rush, and weak at safety, Arizona's defense is quietly a 2014 concern after losing Karlos Dansby in free agency and Daryl Washington to suspension.

Cardinals FS Rashad Johnson suffered a high ankle sprain in Week 15 against the Titans.

It's a concern for Arizona's backend because it just lost Tyrann Mathieu to a double-knee-ligament tear. Johnson can now be considered out indefinitely. If he can't start in Week 16 at Seattle -- and we certainly suspect he won't -- the Cardinals would turn to undrafted rookie Tony Jefferson at free safety.
