The Vikings will sign former Titans S Michael Griffin, according to the Minneapolis Star Tribune. Look for the team to create some sort of rotation after re-signing SS Andrew Sendejo for $16 million over 4 years. Harrison Smith certainly figures to be play full time. Griffin had flashes of nice IDP production in Tennessee but didn't rate well as a coverage player. We'll see how Minnesota sorts out this group.

The Vikings on Saturday placed S Michael Griffin on IR with a back injury. That clears the way for S Andrew Sendejo to continue starting next to S Harrison Smith. ESPN reports that Griffin plans to get a 2nd opinion on his back. There's a chance he could gain release from the Vikings and be free to sign elsewhere, but odds stand against him proving fantasy-relevant for IDP owners in 2016.

Titans S Michael Griffin will miss today's game against the Falcons with a knee injury. That's no huge loss to the Tennessee pass D or IDP owners.

The Titans list S Michael Griffin as questionable for Sunday's game against the Falcons. Griffin started the week on the sideline before seeing limited practice time with a knee injury. He'll carry some upside if active but isn't worth waiting on unless you play in a deep IDP league.

As expected, Titans S Michael Griffin is active and starting against the Jets today despite dealing with a back injury during the week. He progressed to a full practice Friday and looks fine to use in your IDP lineup as you normally would. The matchup only adds to Griffin's fantasy upside this week.

Titans S Michael Griffin is questionable for Sunday's game against the Jets because of a back injury. Griffin put in a full practice Friday, though, after missing Wednesday's workout and returning for a limited Thursday practice. We'd bet on Griffin playing Sunday. The 4:05 p.m. ET kickoff means that you'll need to wait to make sure he's active, but teammate George Wilson can serve as an insurance option for your IDP lineup. Other late-game insurance DBs include Jets S Jaiquawn Jarrett, Lions S Glover Quin and Cowboys S J.J. Wilcox. Check our Week 15 DB rankings for the best available DBs for your matchup.
