The Dolphins announced a series of transactions Tuesday morning, including the signing of one rookie quarterback and the release of another.
The Dolphins added three players, including Seth Lobato, an undrafted free agent quarterback from Northern Colorado. The 23-year-old Lobato completed 56.6 percent of his passes in his collegiate career (637-of-1126), throwing 53 touchdowns. The Colts waived Lobato (6-6, 223) in June.
The Dolphins also signed tight end Brett Brackett (6-5, 246) and defensive end D’Aundre Reed (6-4, 260). Brackett, 26, was with the Cardinals earlier in the offseason, while the 26-year-old Reed was let go by the Jaguars in April. Reed was active for six games with Minnesota in 2012.
To make room for the three additions, the Dolphins waived three undrafted rookies: quarterback Brock Jensen (North Dakota State), linebacker Derrell Johnson (East Carolina) and offensive guard Davonte Wallace (New Mexico State). Wallace was waived-injured.
