Tony Carter has become the fourth Bronco to sign his free-agent tender this offseason, following Lance Ball, Chris Clark, and Mitch Unrein.
As with Unrein's case, Carter's signing is pure formality, as the corner had no opportunity to negotiate or sign with other teams due to his exclusive rights status.
The FSU alum will turn 27 next month, and enters his fifth season in the NFL after not having been invited to the national scouting combine.
Carter scored two defensive touchdowns in 2012, the first a 65-yard fumble return in San Diego during Denver's wild MNF comeback, and the second a 40-yard pick six of Carolina quarterback Cam Newton.
His other interception on the season came later during that same San Diego game, and he also recorded a fumble recovery on a muffed punt by Trindon Holliday at Oakland in Week 14.
In 15 regular season games (511 snaps), Carter was credited with 12 passes defensed and 24 total tackles, while Pro Football Focus gave him a +4.8 grade over 558 snaps, including Denver's playoff loss to Baltimore.
Carter will draw a $715K salary this season if he makes Denver's 53-man roster, and is scheduled to become a restricted free agent next offseason.
Only Ryan Clady (franchise) and Britton Colquitt (restricted) remain unsigned among the players Denver tendered this offseason.
