Dolphins add DL Cam Rice to 90-man roster, waive safety Tanner Wall

The Miami Dolphins announced that they have signed defensive lineman Cam Rice to their 90-man roster, a move that reshapes the team’s defensive depth during the preseason roster-management window.

The transaction came with a corresponding roster adjustment, as the Dolphins waived safety Tanner Wall in order to make room on the same 90-man limit.

For teams at this point of the offseason, additions like Rice’s typically serve a specific purpose: evaluating pass-rush ability, run-defense fit, and overall performance in team sessions where coaches can sort through a crowded group of players trying to earn or retain a spot.

Defensive line rotations often carry a premium value, not only for starters but also for the “third-and-down” and “next-man-up” roles that determine how well a defense sustains pressure across multiple series.

The Dolphins’ decision to pair the Rice signing with the Wall waiver also reflects how NFL teams balance position groups. Even when the move is small on paper, shifting one roster spot can influence practice reps, special-teams opportunities, and the pecking order among safeties and down-linemen.

Wall’s waiver means he becomes available to other clubs, while Rice’s arrival gives Miami another look at how its defensive line group can handle different blocking schemes and generate interior disruption.

What to watch next is whether Miami keeps Rice through subsequent roster reductions or whether the move turns into a short-term evaluation before additional cuts. If the Dolphins bring in more players, the priority will likely remain clarity in the front-seven rotation and the defensive secondary’s depth behind the starters.
