The Facts: James Walker of ESPN.com reports that the team has signed Fales as a free agent. He joins Ryan Tannehill, Matt Moore and Brandon Doughty on the depth chart.

Diehards Line: Fales was a sixth-round pick of the Bears in 2014 and spent two years with the team, including one when Dolphins HC Adam Gase was Chicago’s offensive coordinator, before getting cut last September. The Dolphins have said that Tannehill’s knee is healed after the injury that kept him from playing in the final weeks of last season, but Fales’ presence gives them someone else to take reps and avoid overtaxing Tannehill during offseason work. As PFT suggests, how Fales fares in that work will likely impact whether he sticks around as a third quarterback beyond the offseason.
