Dolphins Sign Marques Cox and Carlos Washington Jr., Waive Jalin Conyers and Braeden Daniels

The roster changes signal Miami is favoring players who can compete immediately for depth spots.

Overview

  • The Miami Dolphins posted on X on Thursday that they signed offensive tackle Marques Cox and running back Carlos Washington Jr. and waived tight end Jalin Conyers and guard/tackle Braeden Daniels.
  • The Conyers cut surprised local reporters after he made visible plays in recent OTAs and because he entered 2025 with strong college receiving totals and a high PFF run-blocking mark.
  • Marques Cox joined Miami after spending 2025 on Broncos and Cardinals practice squads and being released by Denver on May 8, and the team expects him to compete for a back-end tackle role.
  • Braeden Daniels was released after an early-career torn rotator cuff and multiple practice‑squad moves left him without a regular-season snap for the NFL.
  • The moves reflect changes to Miami’s tight end room following the draft additions of Will Kacmarek and Traore and the re-signing of Greg Dulcich, and they set up fresh competition to watch through OTAs and training camp.
