Dolphins Activate Defensive Tackle Kenneth Grant, Make Practice Squad and Waiver Moves

The Miami Dolphins made a set of roster changes on Saturday that included activating defensive tackle Kenneth Grant from injured reserve, according to ESPN’s Marcel Louis-Jacques as reported by Pro Football Rumors. The move indicates Miami’s intent to add Grant’s interior presence back into its active rotation at a point of the season when depth up front often becomes a weekly requirement.

Along with Grant’s return, Miami waived quarterback Brady Cook. In NFL roster terms, a waiver does not automatically mean the player is gone from the organization’s football plans, but it does create uncertainty, since other teams can claim him and force a new destination. For the Dolphins, it is also a reminder that the margin for error at quarterback is thin, particularly when teams are adjusting the active roster week to week.

Miami also elevated running back Carlos Washington from the practice squad, a move that typically indicates a need for additional ball-carrier options on game day, whether for touches, special teams snaps, or matchup-specific use. Practice squad elevations can be a way to keep a player active without permanently consuming roster space, giving coaches flexibility as they react to injuries and game plans.

In the same wave of moves, the Dolphins elevated defensive lineman Rodney McGraw from the practice squad. Adding a defensive lineman through elevation suggests Miami is prioritizing rotation and freshness along the front, which can matter both for run defense and for generating pass-rush opportunities over the course of four quarters.

Put together, the Grant activation plus the two practice squad elevations points to a Dolphins roster management strategy that emphasizes controllable personnel changes. Instead of only relying on permanent additions, the club is using activation and elevation mechanisms to adjust its active group while retaining the practice squad as a pool for the next set of needs.

For Grant specifically, activation from injured reserve means the Dolphins believe he can contribute at the active level now. Defensive tackles play a specialized role, and the decision to bring one back is often tied to how the coaching staff expects blocking schemes and run fits to look ahead. Even when a returning player is not expected to lead the snaps immediately, having him available can allow Miami to structure its defensive packages more comfortably.

What to watch next is whether these moves stabilize the Dolphins’ lineup in the immediate week ahead, or whether Miami continues to cycle through the edges of its roster. Since practice squad elevations are often temporary, the key question becomes whether Washington and McGraw remain active after the next roster reset, and whether the waived quarterback, Cook, stays within Miami’s orbit or is claimed elsewhere.
