Core Moves Impacting the Quarterback Room
- The Miami Dolphins traded quarterback Quinn Ewers to the Jacksonville Jaguars for a 2028 sixth-round draft pick.
- The team waived backup quarterback Cam Miller.
- Rookie quarterback Mark Gronowski remains on the roster tracker, but the Dolphins have indicated they may waive him and later re-sign him to the practice squad.
Background & Context
The NFL requires each club to cut its preseason roster from 90 players to a 53-player regular-season limit by the 6 p.m. Eastern deadline on Sunday. After waiving 12 players on August 29, the Dolphins entered the final stage with 78 players, having already traded Ewers.
Quarterback Personnel Details
| Player | Status | Recent Activity | Preseason Stats |
|---|---|---|---|
| Malik Willis | Active roster starter | Remains the sole quarterback on the 53-man list | — |
| Cam Miller | Waived | 2025 sixth-round pick of the Las Vegas Raiders; signed from the Raiders’ practice squad in January | Completed 42.1% of passes for 170 yards with two interceptions in three preseason games (NBC Sports; USA Today) |
| Mark Gronowski | Undrafted rookie; waiver pending | Signed as an undrafted free agent, waived in early August, re-signed two weeks later | Completed 46.2% of passes for 98 yards, no touchdowns or interceptions; rushed for 37 yards and lost one fumble |
NFL Network analyst Mike Garafolo reported that the Dolphins plan to waive Gronowski but hope to bring him back on the practice squad.
Official Statements & Responses
NFL insider Adam Schefter posted on X that the Dolphins are waiving Cam Miller, creating a need at the No. 2 quarterback spot. Schefter also confirmed the release of wide receiver Terrace Marshall Jr., indicating broader roster adjustments.
Roster Implications & Next Steps
With only Malik Willis confirmed on the active roster, Miami must either retain Gronowski on the practice squad or acquire another quarterback before the 6 p.m. deadline. Projections from “The Phinsider” list only Willis making the final 53, projecting both Miller and Gronowski to be cut and noting that the backup quarterback position remains unfilled.
Data & Statistics Summary
- Cam Miller: 42.1% completion rate, 170 passing yards, two interceptions (preseason).
- Mark Gronowski: 46.2% completion rate, 98 passing yards, 0 TD/INT, 37 rushing yards, one fumble (preseason).
- Roster size: 78 players after the August 29 cuts; must be reduced to 53 by the upcoming deadline.
Conflicting Reports & Gaps
Sources differ on Gronowski’s future: Garafolo suggests a possible practice-squad signing, while “The Phinsider” projection assumes his release. The Dolphins have not issued a public statement confirming any practice-squad move, leaving the backup quarterback situation unresolved.
