The Miami Dolphins have announced roster moves, waiving four players and releasing one. The team waived defensive back Damarr Aultman, wide receivers Tyler Davis and Robert Herron and defensive tackle Robert Thomas II, while releasing linebacker Terrell Manning.
Aultmann spent the 2015 preseason with the Dolphins, playing wide receiver, before being waived at the start of last season. He re-joined the team on a reserve/futures contract in January.
Davis joined Miami on a reserve/futures contract in January after spending two seasons in the German Football League.
Herron was a sixth-round draft pick of the Tampa Bay Buccaneers in 2014, playing in eight games as a rookie. He spent the final 12 weeks of the 2015 season on the Dolphins' practice squad before signing a reserve/futures contract in January to stay with Miami.
Thomas began his NFL career with the Washington Redskins in 2014. He spent the first portion of the 2015 season with the New England Patriots on their practice squad before signing in December with the Dolphins. He appeared in one game for Miami before suffering a season-ending injury and being placed on injured reserve.
Manning entered the NFL as a fifth-round pick of the Green Bay Packers in 2012. He also spent time with the San Diego Chargers in 2013 and the New York Giants and Chicago Bears in 2014 before multiple stints on the Dolphins' practice squad in 2014 and 2015. He signed a reserve/futures contract with Miami in January.
The Dolphins currently have 73 players on their roster, out of a 90-player limit. They currently have eight selections in the NFL Draft, which begins later tonight, giving them, nine roster spots available for undrafted free agents or other free agent signings after the Draft.
