Dolphins waive QB Cam Miller as they trim to the initial 53-man roster

The Miami Dolphins have reportedly waived backup quarterback Cam Miller as the team works through the league’s roster-cut window and prepares its initial 53-man roster. Multiple reports, including Yahoo Sports, framed the move as part of the Dolphins’ effort to consolidate their quarterback group heading into the next phase of camp.

The waiver would leave Mark Gronowski, an undrafted rookie, as the only quarterback listed behind Malik Willis if Miller does not return in a different capacity. The Dolphins have not indicated publicly through the available reporting that Gronowski is guaranteed a spot beyond the final cuts, which keeps the later stages of the quarterback battle and depth-plan in flux.

The Dolphins’ actions come after another notable early-camp adjustment to the position. According to the same report, Miami traded Quinn Ewers to the Jacksonville Jaguars on Saturday, further changing the composition of the depth chart and reducing the team’s tolerance for keeping multiple developmental quarterbacks.

For the Dolphins, the timing underscores how quickly teams must balance roster math with the need to carry enough quarterback depth for practices, emergencies, and the realities of preseason snaps. Because the NFL requires teams to finalize their roster by the deadline, decisions like these often land in quick succession as staffs evaluate late-season readiness, practice performance, and whether an additional developmental arm is worth a roster slot.

While the report describes the Dolphins waiving Miller, the details of the waiver process and whether Miami intends to pursue Gronowski or another quarterback through alternative channels were not included in the available material. That means the situation could still evolve if another team claims Miller or if Miami later re-adds a passer through practice squad or other roster mechanisms.

The immediate question for Miami becomes whether it wants to keep more than one developmental quarterback behind Willis, or whether it will use other roster categories to create the coverage needed at the position. With camp continuing through the cut period, the Dolphins’ remaining quarterback depth will be watched closely, particularly any late addition that could alter Gronowski’s odds of surviving the final wave of cuts.

For fans and observers, this is a reminder that quarterback depth decisions can reflect more than simple ability. They often report how a team is prioritizing reliability, learning curve, and game-ready skill sets for the coming season, even when those choices involve players still fighting for a roster role.
