Johnson has announced his retirement from the NFL, according to his personal Instagram account.

EDGE Analysis

Johnson decided to call it quits on his 32nd birthday, retiring from the NFL after eight seasons. He most recently racked up 38 tackles (25 solo) and one pass defensed in 14 games with the Titans throughout the 2016 season. Prior to that, he spent seven years with the Cardinals, totaling 382 tackles (306 solo), one sack, 31 passes defensed, 15 interceptions and three touchdowns during his career.

Johnson missed each of the Titans' last two games with a neck injury. Now back at practice -- and participating without limitation -- he appears set to play this weekend against the Packers.

EDGE Analysis

Johnson has been sidelined the previous two weeks as he has dealt with a neck injury. The team appears optimistic regarding a potential return Sunday. Daimion Stafford would presumably be in line for another start at free safety if Johnson experiences any setbacks.

Johnson (neck) has been ruled out for Thursday's game against the Jaguars.

EDGE Analysis

Johnson wasn't able to practice throughout the week due to the neck issue, and will therefore be unable to play in the Titans' Week 8 matchup. Kevin Byard figures to get the start at free safety in Johnson's absence.

Johnson has signed a one-year deal with the Titans, ESPN's Josina Anderson reports.

EDGE Analysis

Despite missing two games last year due to an ankle injury, Johnson put up solid numbers at safety for the Cardinals, amassing 61 tackles (50 solo) and five interceptions. With the Cardinals appearing disinterested in re-signing their safety during the offseason due to age concerns, the 30-year-old safety will likely battle with former fourth-round pick Marqueston Huff for the starting free safety spot in what amounts to a "prove-it" type deal.

Johnson is an unrestricted free agent this offseason.

EDGE Analysis

Sidelined in Weeks 15 and 16 due to an ankle injury, Johnson still amassed 61 tackles (50 solo), five interceptions, and one fumble recovery during the regular season. In his return in the season finale, he received just 39 of 72 defensive snaps, but the Cardinals' bye week allowed the safety to log every one of those snaps in their two playoff tilts. Johnson has called the Arizona desert his home since he was drafted in 2009. However, his age (30) may cause the front office to balk in contract negotiations in favor of fresher legs.
