Mosley signed a one-year deal with the Dolphins on Wednesday, Adam Schefter of ESPN reports. Mosley will join forces with Ndamukong Suh for the third season in a row, but a training-camp battle with Earl Mitchell will likely determine Suh's running mate at defensive tackle. In 31 games between 2013 and 2014 with the Lions, Mosley racked up 42 tackles (29 solo), 2.5 sacks, two forced fumbles, and one fumble recovery.
