Free agency tracker

NFL free agency officially started at 3 p.m. CT. The Vikings have already made a few moves but could be in the hunt for a few more defensive players. Cornerback and defensive tackle are two positions to watch now they're able to sign unrestricted free agents from other teams.

Here are the latest transactions that have hit the wire to this point, including players the Vikings were interested in and other moves around the NFC North:

*The Colts will sign Ravens defensive tackle Arthur Jones, according to multiple reports. The Vikings made contact with Jones' representation during the three-day negotiating window.

*The Bears reached a five-year deal with Raiders defensive end Lamarr hunt worth $35 million, according to multiple reports. The Vikings re-signed defensive end Everson Griffen on a five-year, $42.5 million deal.

*The Bears will re-sign linebacker DJ Williams to a one-year deal, according to NFL.com.

Update (3:41 p.m.):

*The Falcons will sign Dolphins defensive tackle Paul Soliai, the team announced. The Vikings reportedly made contact with Soliai's representation during the three-day negotiating window. It's a five-year deal worth $33 million with $14 million guaranteed. Defensive tackles have seen more action in the first hour of free agency than cornerbacks surprisingly.

*Now we've got some action at cornerback. Colts have re-signed cornerback Vontae Davis, the team announced. It's a reported 4-year deal worth $39 million with $20 million guaranteed.

As more deals are reported, you probably shouldn't feel bad anymore that the Vikings overpaid for Griffen. It's a good year to be a NFL free agent.

Update (4:14 p.m.):

The Jaguars have traded quarterback Blaine Gabbert to the 49ers for a sixth-round pick, according to multiple reports. This has been the biggest surprise so far. The 49ers already have Colin Kapernick and Gabbert will earn $2 million next year.

Maybe Vikings quarterback Christian Ponder does have some trade value after all...

The Vikings will sign defensive tackle Linval Joseph, according to an NFL source. It's a five-year deal worth $31.5 million, according to ESPN.

Joseph, 25, has spent all four seasons with the Giants. He's listed at 6-4, 323 pounds and will solidify the nose tackle position on the defensive line. Joseph had 59 combined tackles last season with three sacks and one forced fumble.

The Vikings starting defensive line seems to be set now with Joseph, defensive ends Brian Robison and Everson Griffen and defensive tackle Sharrif Floyd, who will serve as the three-technique tackle in Vikings head coach Mike Zimmer's scheme.

Update (6:05 p.m.):

The Vikings will re-sign offensive lineman Joe Berger to a one-year deal, according to an NFL source.

Update (9:05 p.m.)

Vikings running back Toby Gerhart will sign with the Jaguars on a three-year deal worth $10.5 million with $4.5 million guaranteed, according to multiple sources. He's the first Vikings unrestricted free agent to sign with another team so far. Gerhart wasn't expected to return back to the team with Adrian Peterson serving as the team's lead running back.
