The Miami Dolphins have signed seven players to reserve/futures contracts. These players are now considered part of the Dolphins organization, even though their contracts do not officially take effect until the new league year starts in March.
An NFL "reserves/futures contract" can be signed by any player not on a team's roster at the end of regular season. Typically, teams will sign their own practice squad players back to the team using reserve/futures contracts. Any player from a practice squad around the league could, theoretically, sign with any team.
The players will be with the team through the offseason and preseason, trying to secure a roster spot.
According to the Miami Herald's Adam Beasley, the Dolphins players signed by the team are guard Chandler Burden, tackle Jeff Adams, defensive tackle Chas Alecxih, wide receiver Jeff Fuller, tackle Andrew McDonald, defensive back DeAndre Presley, and wide receiver Brian Tyms. All seven players spent at least a portion of the season with the Dolphins.
