Griffin signed a one-day contract to retire with the Titans, Nick Shook of NFL.com reports.
Griffin was selected by the Titans in the first round of the 2007 NFL Draft and went on to appear in two Pro Bowls (2008, '10) and earn one Second-Team All-Pro nod ('10). He last appeared in the NFL in 2016 for the Panthers, making six starts in 13 games. The 33-year-old safety retires with 803 tackles, 25 interceptions, 12 forced fumbles, six fumble recoveries and seven sacks in 154 career regular-season games.
Griffin recorded a team-high 14 tackles in Sunday night's loss to the Seahawks.
Griffin's 14 tackles nearly doubled his season total, as the veteran now boasts 30 stops through nine games with the Panthers this season.
Griffin (back) signed a one-year contract with the Panthers on Tuesday.
Griffin, a 10-year veteran, signed with the Vikings during the offseason but was cut by the team before the start of the season after being placed on injured reserve due to a back injury. The Panthers have not commented on the health status of Griffin, but look for updates to come later in the week. Once healthy, Griffin could potentially compete with Kurt Coleman for the starting job at strong safety.
Griffin (back) reached an injury settlement with the Vikings on Wednesday, Anthony DiMoro of the Huffington Post reports.
The agreement removes Griffin from the Vikings' injured reserve list. When healthy, he'll be free to sign with another organization.

With Griffin hurt, Andrew Sendejo will begin the season as the starting strong safety next to Harrison Smith.
Griffin got the start at safety opposite Harrison Smith in Sunday's preseason game, but left in the second quarter due to a back injury and was later seen leaving the locker room on crutches, ESPN 1500 am Twin Cities reports.
Griffin had one tackle before departing. He got the start in the third preseason game over Andrew Sendejo, but head coach Mike Zimmer indicated the competition for the second safety spot isn't decided. However, Griffin's injury could make Sendejo the starter if it's an issue for the start of the regular season.
Griffin started at safety opposite Harrison Smith in Thursday's preseason win over Seattle. The competition for the starting safety job opposite Smith will likely be decided late in the preseason, the Minneapolis Star Tribune reports.
Andrew Sendejo started opposite Smith in the first preseaon game, so it looks like an even competition at this point with Antone Exum, Anthony Harris and Jayron Kearse also in the mix. Griffin had two tackles and a sack in Thursday's game.
The Vikings have signed Griffin, the Minneapolis Star-Tribune reports.
Per the report, the addition of Griffin could well send Andrew Sendejo to a backup role. The 31-year-old Griffin is coming off back-to-back IDP-relevant campaigns with the Titans, including 2015, when he recorded 101 tackles in 15 games.
Griffin has been released by the Titans, John Glennon of The Tennessean reports.
The 19th overall pick in the 2007 NFL Draft, Griffin played 14 or more games in each of his nine years in Tennessee. The 31-year-old safety is coming off back-to-back seasons with 100+ tackles, but he's become a liability in coverage and was scheduled for an $8.3 million cap hit in 2016. If he's able to land a starting gig elsewhere, he could still be a productive IDP.
Griffin recorded 11 tackles (nine solo) in Sunday's 34-6 loss to the Texans.
The veteran safety has always been excellent against the run, and his contributions helped limit the Texans to 3.0 yards per carry in what was otherwise an atrocious all-around effort by the Titans. Griffin should get plenty of opportunities to pad his tackle numbers against the Colts next week, as Indianapolis is expected lean on running back Frank Gore after he gashed the Titans for 86 yards and two touchdowns back in Week 3.
Griffin recorded nine tackles (seven solo) in Sunday's 42-39 win over Jacksonville.
This was not a pretty game for either defense, but Griffin's sure tackling went a long way toward helping the Titans pick up a win. The 30-year-old safety has 73 tackles in 11 games played this season after recording a career-high 112 in 2014.
Griffin (knee) recorded a season-high nine tackles (six solo) in Sunday's 20-6 loss at Houston.
The 30-year-old safety returned with a vengeance after missing last week's tilt against Atlanta. Griffin and the defense have gotten plenty of opportunities to pile up tackles in recent weeks, as Tennessee's inept offense has failed to sustain long drives.
Griffin (knee) is listed as active for Sunday's game against the Texans.
Griffin - who racked up 112 tackles and two picks last season - checks back into the Titans' lineup with 27 tackles and a pick through five games, numbers to give him a degree of IDP utility when he is healthy.
Griffin (knee) is listed as probable for Sunday's game on the team's official injury report.
While Griffin hasn't officially been ruled available, Titans Online writer Jim Wyatt said the 30-year-old is expected to play against the Texans after missing last week's game with a knee injury. If that does wind up being the case, Daimion Stafford will likely slot back into his reserve role in the secondary.
Griffin (knee) was a full participant in practice Thursday, Jim Wyatt of Titans Online reports.
Griffin missed last week's game due to a knee injury, but was able to return to practice Wednesday on a limited basis. Obviously Thursday's news is a great sign for his chances to suit up in Week 8, however the Titans have yet to officially rule Griffin available. That designation will likely come Friday following another full practice.
Griffin (knee) was limited in practice Wednesday.
Griffin continues to recover from the knee injury that kept him on the sidelines for the Titans' Week 7 loss against the Falcons. His status should be monitored throughout the week, as he remains questionable for Sunday's matchup against the Texans.

Griffin (knee) did not practice Wednesday.
His injury comes as a bit of a surprise considering he was able to play through most of Sunday's game against the Dolphins. More information regarding the 30-year-old's status for this week's contest against the Falcons will likely come later in the week.
