Check out a round-up of the first day of NFL free agency

AFC South

• The Tennessee Titans announced they will release veteran QB Vince Young and immediately replaced him with Matt Hasselbeck, who today agreed to terms. Less than a day after the Seattle Times reported that Hasselbeck would not be re-signing with the Seahawks, the veteran quarterback found a new home. Hasselbeck started for the Seahawks since 2002, and led them to a surprising playoff win over the New Orleans Saints in 2010.

• The Jacksonville Jaguars looked to shore up their defense by signing former Bills linebacker Paul Posluszny to a six-year deal worth over $45 million. After losing two starting linebackers — Justin Durant and Kirk Morrison — the Jags needed to add to their defensive front seven.

• The Houston Texans re-signed wide receiver Jacoby Jones and running back Rashad Butler. They also reportedly agreed to terms with QB Matt Leinart.

AFC East

• The Buffalo Bills were another team to make a move at quarterback, agreeing to a three-year contract with free agent Tyler Thigpen.

• The Miami Dolphins are reportedly in contract talks with Kyle Orton, the former Broncos QB who was placed on the trading block at the start of the free agency period.

• The New York Jets held on to free agent Santonio Holmes, despite interest from teams such as the Washington Redskins . Holmes and the Jets agreed to a five-year deal worth up to $10 million a year.

AFC West

• The Denver Broncos acquired defensive end Jeremy Jarmon in a trade with the Washington Redskins for wide receiver Jabar Gaffney, who will join a growing list of Redskins receivers.

• The San Diego Chargers signed tight end Randy McMichael, linebacker Takeo Spikes and tackle Jeromey Clary. On the defensive side they also signed safety Bob Sanders to a one-year contract.

AFC North

• The Baltimore Ravens agreed to terms with offensive lineman Marshal Yanda for a five-year deal using salary cap space cleared when they released Willis McGahee, Todd Heap and Kelly Gregg.
