One of the Dolphins’ better success stories in 2025 is officially headed elsewhere — but Miami may still benefit from his departure

The Miami Dolphins will, officially, not have Jack Jones back in 2026. He’s signing a one-year deal with the San Francisco 49ers.

The Miami Dolphins‘ overhauled secondary is guaranteed to have one less familiar face.

After an exodus of talent on the defensive back end in recent years, Miami is once again going back to the drawing board in the secondary. Jalen Ramsey, Jevon Holland, Xavien Howard. Kendall Fuller, Jordan Poyer, DeShon Elliott, Brandon Jones, and more. All have all come and gone in recent years. Now, one of the team’s better successes from 2025 is officially off to greener pastures, too.

Jack Jones to sign in San Francisco, puts Miami Dolphins on 2027 compensatory pick watch

According to reports, Jack Jones is signing a one-year contract with the San Francisco 49ers. The move comes after a visit with the team on Friday. A signing was possibly telegraphed in part by Jones changing his representation recently. He’s now repped by super-agent Drew Rosenhaus.

The departure is not a surprise. But it does open a new storyline to watch for the Dolphins.

Depending on the cost that the 49ers are paying Jack Jones, it does open the door for Miami to be eligible for a compensatory pick for his loss. Miami is currently projected to receive a 7th-round pick for the departure of Larry Borom in free agency to Detroit. Borom signed a one-year deal worth $5 million.

But given the lack of other high-priced free agents, Jones’ departure could swing Miami another pick. Basically, the Dolphins would likely need Jones’ contract value to surpass $4 million to currently qualify for a projection.

These compensatory picks are predicated on playing time. Accordingly, the Dolphins are not guaranteed anything on this front unless Jones lands a bigger deal than those contracts that currently sit on the bubble. Miami is currently stockpiling assets — so every little bit counts. We’ll need to see where the Jones contract falls before determining if there’s a benefit to his departure for Miami or not.
