Johnson picked off two passes and recovered a fumble during Sunday's victory at Detroit.

Since posting one tackle in the opener, Johnson has totaled 22 tackles over the last four games, but his value rests in his ability to force turnovers. Lo and behold, he notched his second and third interceptions of 2015, the latter of which was tipped in the air by Tyrann Mathieu and subsequently sniped by Johnson. Thus continues a trend during the Bruce Arians' era -- 2013 to present -- during which Johnson has nabbed 10 interceptions, including two pick-sixes, and recovered two fumbles in 34 games.

Johnson handled all 72 of the Cardinals' defensive snaps Sunday in Chicago, Mike Jurecki of FOX Sports 910 Phoenix reports.

After picking off Drew Brees in the regular season opener, Johnson responded with seven tackles and a tackle for loss in Week 2. As he soaks up all the reps at free safety, with Tyrann Mathieu filling in as the Cardinals' slot corner (70 snaps Sunday), Johnson will be afforded plenty of chances to contribute to IDP pursuits.

Johnson is listed behind Tyrann Mathieu at free safety on the Cardinals' initial depth chart, Mike Jurecki of FOX Sports 910 reports.

Taking advantage of Mathieu's recovery from knee ligament tears, Johnson burst forth last season, racking up team highs with 93 tackles (76 solo) and four interceptions. He also pitched in two defensive touchdowns, three tackles for loss, one sack, and one fumble recovery to become one of the surprise IDPs of 2014. Along the way, he earned 99.2 percent of the defensive snaps, according to Football Outsider, which should experience a downturn with a reduced workload in the coming campaign.

Johnson notched team highs with 93 tackles (76 solo) and four interceptions for the Cardinals during the 2014 season.

In addition to the aforementioned career-best marks, Johnson also tallied two of Arizona's three defensive touchdowns (both via pick), while recording three tackles for loss, one sack, and one fumble recovery. According to Football Outsiders, he easily led Cardinals' defensive backs by logging 99.2 percent of the defensive snaps, which is impressive in a corps composed of Pro Bowlers Patrick Peterson and Antonio Cromartie. Moreover, Johnson successfully fended off 2014 first-round pick Deone Bucannon for the entirety of the season, meaning the six-year pro enters the offseason as the unquestioned starter at strong safety.

Johnson (ankle) is listed as active Sunday in San Francisco, the Cardinals' official site reports.

Johnson will take on his normal spot in the starting lineup at free safety in his quest to add to a career season (89 tackles, four interception, two touchdowns, one sack, and one fumble recovery).

Johnson supplied six tackles (four solo), one quarterback hit, and an 88-yard interception return for a touchdown in Sunday's loss at Atlanta.

Facing a 17-0 deficit with the Falcons again knocking on the door early in the second quarter, Johnson provided some breathing room for a time by jumping a Julio Jones route and taking it to the house. The pick marked Johnson's second in three contests, and fourth on the season, which equates to a career-best total for the six-year pro. Additionally, his 76 tackles leads the Cardinals and ranks 10th among the league's defensive backs, ensuring his viability across the IDP landscape.

Johnson totaled a team-high nine tackles (six solo) during Sunday's defeat in Seattle.

According to FOX Sports 910 Phoenix, Johnson logged all 58 of the Cardinals' defensive snaps, joining fellow defenders Patrick Peterson and Larry Foote in that regard. Johnson continues to take advantage of significant usage, as his Week 12 tackle total marks his second-best performance of the season. Furthermore, with 70 stops through 11 contests, he sits in a tie for 10th among the league's defensive backs, solidifying himself as an IDP mainstay.

Johnson (back) active for Sunday's contest at Seattle, the Cardinals' official site reports.

Johnson factors into the Cardinals' defensive backfield on most snaps, which has afforded him significant IDP value this season. He'll attempt to build upon 61 tackles (53 solo), seven passes defended, three interceptions (one for a touchdown), one sack, and one fumble recovery in 10 outings.

Johnson (back) is probable for Sunday's game against Seattle.

Johnson has shown borderline DB1 IDP utility this year, and he ought to provide similar upside against Seattle this week.

Johnson (back) was limited in Thursday's practice, Darren Urban of the Cardinals' official site reports.

Johnson picked off his third pass of the season in Week 11, which aided in the Cardinals' tight victory over the Lions. Because Arizona utilizes six defensive backs on most snaps, he isn't without significant opportunity on a weekly basis due to the other names in his backfield, in particular Patrick Peterson and Antonio Cromartie.

Johnson took the field for all 92 of the Cardinals' defensive snaps in Sunday's win versus the Eagles, Mike Jurecki of FOX Sports 910 reports.

As a result, Johnson ranked second on the team in tackles with 11 (10 solo), while recording a whopping four passes defended. Because the LB corps has been decimated by a confluence of events, defensive coordinator Todd Bowles has hung his hat on a deep secondary, with six defensive backs playing at least 79 percent of the snaps Sunday. However, both Patrick Peterson and Tony Jefferson have entered the concussion protocol, which could place some additional strain on the remaining defensive backs in a Week 9 showdown at Dallas. No matter, as the owner of 47 tackles (42 solo), two picks (one for a touchdown), one fumble recovery, and one sack in seven contests, Johnson should continue to aid IDP pursuits.

Johnson (knee) is listed as active Sunday versus the Eagles, the Cardinals' official site reports.

Johnson attained a full practice by week's end, which should equate to a majority of the defensive snaps once again in Week 8. Until Tyrann Mathieu displays the ability to handle a full workload, Johnson will handle most of the reps at free safety, allowing him pile on to his 36 tackles (32 solo), two interceptions (one for a touchdown), one sack, and one fumble recovery in six contests.

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.
