Dolphins Sign CBs Darrell Baker, A.J. Green, Alex Austin

The Dolphins continue to make additions on defense. Cornerback Darrell Baker has agreed to terms on a one-year deal, per his agents (via Tom Pelissero of NFL Network).

In addition, the team has announced the signing of fellow corner A.J. Green. Those two will join a new-look secondary in 2026. Miami agreed to terms with Lonnie Johnson Jr. earlier today. And to top it all off, the Dolphins have agreed to a one-year deal with cornerback Alex Austin, per Jordan Schultz.

Baker is coming off a two-year stint with the Titans, where he emerged as a part-time starter. He started 19 of his 34 appearances between 2024 and 2025, collecting 95 tackles and 12 passes defended. He primarily played as an outside cornerback during his stint in Tennessee, although he also made same cameos at safety, at slot corner, and in the box.

The former UDFA out of Georgia Southern started his career with the Cardinals before catching on with the Colts practice squad. After making only three appearances with Indy as a rookie, he got into 14 games (six starts) in 2023. He inked a one-year extension with the organization during the 2024 offseason, but he was waived by the Colts at the end of that year’s preseason.

Green had a four-year stint with the Bengals to begin his professional career. He’s since bounced around a bit, spending time with the Vikings, Rams, and Dolphins. He split the 2025 campaign between Miami and Los Angeles, where he mostly appeared on special teams.

Austin spent the majority of his three-year career in New England, where he got into 26 games. He started six games during his Patriots tenure (including two in 2025), but he mostly earned his worth on special teams. Austin got into 220 ST snaps during his time in New England, including 120 this past year.
