The Miami Dolphins made a series of roster moves on Sunday, adding two players while waiving one. The team added linebacker James Davidson and guard Bryant Browning, while waiving tight end Arthur Lynch.
Davidson was signed by the Cincinnati Bengals as an undrafted free agent in 2014 and started the season on the practice squad. He was then signed to the New York Giants active roster, appearing in two games, before being waived and becoming a free agent in May 2015.
Browning comes to Miami after entering the league in 2011 as an undrafted free agent, signed by the St. Louis Rams. He spent most of the 2011 season on the Carolina Panthers practice squad, appearing in one NFL game late in the season. He split the 2012 season between the Panthers and the Cleveland Browns practice squads. After a brief offseason stint with the New York Giants in 2013, Browning was on the Buffalo Bills practice squad for the 2013 season. He spent 2014 with the Pittsburgh Steelers, both on the 53-man roster and the practice squad.
Lynch was drafted in the fifth round of the 2014 NFL Draft by the Dolphins. He spent all of his rookie season on injured reserve after injuring his back during training camp. This season, he started slowly in camp, and, with the Dolphins seeing two linebackers suffer injuries during the team's first preseason game, his roster spot was needed for depth on defense. If no one else adds Lynch, he could still return to the Dolphins as a practice squad player next month.
Martin was released after signing as a free agent in July.
