According to the Miami Herald, Mosley visited the Dolphins in Miami on Tuesday and was offered a contract.
The 31-year-old Mosley started eight games for the Lions last season, recording 27 tackles and 2.5 sacks.
Mosley was suspended and sent home before Detroit's game in London last season after reportedly being found with marijuana in his hotel room. He was reinstated the day after the game and finished out the rest of the season.
The Dolphins finished 8–8 last season, coming in third in the AFC East and missing the playoffs.
