Dolphins agree to sign undrafted rookie RB Coleman Bennett to a one-year deal

The Miami Dolphins have agreed to sign undrafted rookie running back Coleman Bennett to a one-year deal, according to ESPN’s Adam Schefter as reported by Yahoo Sports on August 26, 2026. The move gives Miami another body for a position group that typically needs depth and versatility during training camp and the preseason, when teams evaluate multiple runners for roles on early downs, in space, and on special teams.

Bennett’s agreement is notable primarily because it reflects the way NFL teams keep pushing their depth chart as offseason evaluations continue. Undrafted free agents often earn opportunities through a mix of ball-carrying instincts, special-teams value, and the ability to absorb playbook and blocking assignments quickly, especially when a roster is being shaped for the regular season.

For the Dolphins, the decision fits a broader need that repeats every year in the NFL: stable production at running back while maintaining options for injuries, matchups, and situational football. Even when a team has established backs, coaching staffs usually look for traits they can trust in different game scripts, including pass protection and converting short-yardage looks.

Bennett’s deal is described as one year, which also indicates the practical nature of the contract. One-year arrangements for rookies are commonly structured to create roster flexibility while giving the player a clear runway to compete for a job, whether that is as a rotational runner, a practice-squad contributor, or a core special-teams presence.

The timing matters. With training camp in progress and teams nearing the point where preseason reps can be used to separate depth candidates, adding an agreement can help a club manage practice workloads and maintain competition across the room. For Bennett, the Dolphins’ offer represents the next step from college football into the demanding rhythm of an NFL offseason, where consistency and adaptability are tested daily.

There is not enough information in the reported item to confirm Bennett’s college background, physical measurements, or how the coaching staff plans to deploy him. That makes it important to watch what role he carves out over the next few weeks, including whether he gets meaningful reps in practice periods, participates on special teams, and shows the hands, vision, and contact balance teams seek from a sustainable back.

If the Dolphins keep Bennett around into the preseason window, the key question will be whether he can separate himself in limited opportunities. Depth signings like this rarely guarantee a spot by themselves, but they often become pivotal if a player demonstrates specific skills coaches can trust quickly, particularly in pass protection, carry-assist duties, and special-teams coverage. Until more official roster details are released, the agreement should be viewed as the start of Bennett’s competition rather than a finished conclusion about his role.
