Free-agent offensive tackle Dennis Kelly has agreed to a long-term deal to re-sign with the Tennessee Titans, per ESPN's Field Yates.

Kelly, 30, signed a three-year contract with the Titans worth a total $21 million, with $8.75 million guaranteed.

The Titans' agreement with seven-year vet Kelly comes off the heels of the NFL's first day of free agency on Monday, which saw All-Pro offensive tackle Jack Conklin sign a massive three-year, $42 million deal with the Cleveland Browns.

Kelly was a fifth-round selection by the Philadelphia Eagles in the 2012 NFL Draft out of Purdue. After a three-year tenure in Philly, the Eagles traded the 6-foot-8, 321-pound tackle to Tennessee in Aug. 2016 for wide receiver Dorial Green-Beckham.

Kelly wrapped up his four seasons with Tennessee—a campaign that featured an improbable second-half run where the Titans fought for the last spot in the postseason and defeated the New England Patriots and No. 1 seed Baltimore Ravens in the playoffs, only to fall to eventual Super Bowl LIV champion Kansas City Chiefs in the AFC Championship Game.

Kelly appeared in 15 games this past season for Tennessee, making four starts and appearing in 36 percent of the team's offensive snaps, per Pro Football Reference.

The Titans' deal with Dennis Kelly is their highest figure after throwing the bag at Comeback Player of the Year quarterback Ryan Tannehill who, along with star rusher Derrick Henry, led Tennessee's second-half run. Tannehill and the Titans agreed to a four-year extension worth $118 million.

Kelly will no doubt turn into a starter for the Titans now that Conklin is gone, protecting the expensive Tannehill under center.
