Darren Waller missed all of the 2024 season, not because of injury, but because of retirement. The newest tight end on the Miami Dolphins roster just got off to a bad start.
The Dolphins do not disclose information on players' statuses during training camp. They are either able to participate or not. When they can't, they will get a designation of some sort, but the Dolphins do not have to reveal why a player is not able to practice.
In the case of Waller, whom the Dolphins traded future compensation for, the arrival of camp wasn't what he or the team was hoping for.
