Derrick Gunn of Comcast SportsNet Philadelphia was the first to report that Carroll will ink a one-year deal, and Tim McManus of 97.5 The Fanatic later reported the news, via a source. The Eagles went on to confirm the deal.
Ian Rapoport of NFL Network reported Carroll signed a one-year deal worth a base value of $2.36 million. Rapoport added that the deal could be as worth as much as $3 million.
The 29-year-old defensive back spent the first four seasons of his NFL career with the Miami Dolphins before joining Philly prior to the 2014 campaign.
He made 31 tackles in his first season with the Eagles, primarily as a nickel corner, but his role expanded in 2015, as he started 11 games and registered 55 tackles, 10 passes defended and two interceptions.
Pro Football Focus passed along how Carroll graded out in 2015:

The Maryland product missed five contests with a reportedly broken ankle, but he recently posted a video on Twitter that showed him running up stairs and insisting that he didn't break his ankle:

Ankle ain't ever been broke so stop saying it! https://t.co/suX67uJvYt2016-3-2 16:48:04
McManus noted Carroll had surgery on his fibula and should be ready for the start of OTAs, which is great news for an Eagles team that has already experienced a great deal of turnover at corner.
Philadelphia traded Byron Maxwell to the Dolphins and signed former Buffalo Bills cornerback Leodis McKelvin, so Carroll appears to be in line to start full time once again next season.

The Jacksonville, Florida, native is an extremely versatile player who has excelled outside and in the slot over the course of his career, which gives the Eagles and new defensive coordinator Jim Schwartz plenty of flexibility.
Philly will have a different look on both sides of the ball in 2016 under the new coaching regime headed by Doug Pederson, but Carroll's return should give the Eagles secondary some semblance of continuity, which figures to help with the learning curve.
