The Dolphins signed Chosen to the practice squad Thursday.
Chosen appeared in nine regular-season games for the Dolphins in 2023, during which he accrued four catches (on six targets) for 126 yards and one touchdown. He signed with the 49ers in early August to battle for a depth wide receiver spot, but he was ultimately left off the final 53-man roster. Chosen's familiarity with the Dolphins' offense should provide him an opportunity to be elevated to the active roster at some point during the upcoming season.
