The report said it’s a fully guaranteed contract worth up to $3 million.
Branch, 26, was a second-round pick of the Jaguars in 2012 and leaves Jacksonville after four years, mostly as a backup. He started 10 games last season — his first starts since his rookie season — and recorded four sacks.
He had a career-best six sacks in 2013 and has 14 for his career. In Miami he joins a remade pass rush for new defensive coordinator Vance Joseph. Olivier Vernon departed for the Giants, and the Dolphins added Mario Williams on a two-year deal. The Dolphins also lost Derrick Shelby via free agency to the Falcons.
