Carter has signed his exclusive-rights free agent tender that will pay him $715,000 in 2013.
Carter played in a career-high 15 games last season and tied for the team lead with a dozen pass breakups. He also scored touchdowns on a fumble return and on an interception return.

Unrein signed a one-year, $630,000 free-agent tender Thursday with the Broncos.
Unrein, a three-year veteran, also played offense in a goal-line situation for Denver last season. He caught a 1-yard touchdown pass from Peyton Manning to become the first defensive lineman in team history to score on a reception. He has 27 tackles and one fumble recovery over the last two seasons.

Clark signed his $1.32 million restricted free agent tender on Wednesday.
Although Clark has made just a half-dozen starts for the Broncos over the last three seasons, he figures to get plenty of first-team snaps as Peyton Manning's blindside protector when offseason workouts begin. That's because Pro Bowl left tackle Ryan Clady is recovering from right shoulder surgery and is planning to skip the team's offseason program rather than sign his $9.8 million franchise tag.

Ball signed his tender with the Denver Broncos, the team announced Monday. The diminutive but powerful tailback rushed for 158 yards on 42 carries last season as he spelled Willis McGahee and Knowshon Moreno.
Ball has bounced around the league since coming out of Maryland. Originally a college free agent with St. Louis, he made the Rams' practice squad in 2008 before joining Indianapolis that year and making the Colts' active roster for the regular season finale. He also spent time on Tennessee's practice squad before latching on with the Broncos for the last three seasons.
