Dolphins Activate Kenneth Grant, Waive Brady Cook Ahead of Sunday

The Miami Dolphins made several roster adjustments on Saturday, including a return to the active roster for defensive lineman Kenneth Grant. According to the team’s official announcement, Grant was activated off injured reserve, giving Miami another option along the defensive front as game-week preparation continues.

The Dolphins also made a quarterback move, waiving Brady Cook. The transaction indicates that Miami will move forward with a different quarterback group on its roster for Sunday, rather than keeping Cook available as part of the active plan for the week.

On top of those moves, the Dolphins elevated two players to the active roster for Sunday’s game. Edge Rodney McGraw and running back Carlos Washington Jr. were both elevated, expanding Miami’s active set for the coming matchup and reflecting the team’s need to balance roles across defense and the run game.

Taken together, the Dolphins’ moves touch two of the most roster-sensitive areas on an NFL team. Bringing Grant back suggests the team wants more depth or continuity on the defensive line after his time away on injured reserve, while waiving Cook narrows the quarterback room and potentially reshapes how Miami handles practice reps and backup responsibilities during the week.

Elevations like the ones involving McGraw and Washington also underscore how NFL teams manage personnel from week to week. Players promoted to the active roster for a particular game can play a larger role in situational packages, special teams assignments, or offensive rotations depending on matchups and game plans.

While the announcement confirms the transactions themselves, it does not provide additional detail on injuries’ specifics, procedural timing beyond the activation and waiver language, or how these moves will translate into snap counts. Fans will likely see how the active-roster changes affect defensive line rotations, edge rush utilization, and how Washington fits into Miami’s backfield plan.

The next question for Miami is how the updated personnel looks once Sunday’s game is underway. Grant’s activation will be a key storyline on the defensive side, while Cook’s waiver will frame the quarterback depth chart. With McGraw and Washington elevated, the Dolphins will also be looking for immediate contributions from players given the chance to play on the active roster for the first time this week.
