Dolphins add S Tanner Wall to active roster, claim CB Ahmari Harvey off waivers

The Miami Dolphins continued to reshape their defensive back depth on Friday by adding two players through separate transactions. The team announced it has signed safety Tanner Wall to the active roster, and it also claimed cornerback Ahmari Harvey off waivers.

Wall’s addition gives Miami another option in the safety rotation as the club works toward its regular-season defensive staffing. A move to the active roster suggests the Dolphins view him as more than pure camp depth, at least for the immediate stretch of roster construction.

Alongside Wall, the Dolphins’ waiver claim brought in Harvey, a cornerback who had been with the Pittsburgh Steelers before being cut on Thursday. The claim indicates Miami’s willingness to take a chance on a defensive back who was available on short notice, a common approach during late roster reshaping when teams look for traits that can be developed quickly.

From a personnel standpoint, the Dolphins’ double dip points to a specific emphasis: adding back-end coverage bodies during a period when teams evaluate matchups, depth and special-teams fit. Safety and cornerback are both positions that can influence how defenses respond to personnel groupings, particularly in nickel and dime coverages.

For Harvey, the timing is notable. Being released by Pittsburgh on Thursday and claimed by Miami means he will now be brought into the Dolphins’ system rapidly, with limited time for assimilation. Waiver claims typically come with a coaching staff’s quick read on what a player can contribute, even if the ultimate role may not be set immediately.

Miami’s Wall signing also has implications for internal competition. Even if Wall does not start on day one, active-roster status increases the likelihood he will get meaningful practice reps and a clearer path to seeing game action in the final phases of preseason and evaluation.

The next questions for the Dolphins are practical and familiar: how quickly these players pick up coverage concepts, whether they can handle the communication demands at full speed, and how they perform in the small details that determine snap counts. In teams’ defensive building, late additions can become either temporary insurance or the foundation for a deeper rotation.

With roster decisions coming close together, Miami’s defensive back group could look meaningfully different from one week to the next. If these moves pay off, they can tighten the Dolphins’ ability to match up across multiple defensive looks. If they do not, the club likely will continue to churn for the right balance of coverage skills and reliability.
