The Dolphins signed Thomas off the practice squad and to the active roster Wednesday, reports the Miami Herald's Armando Salguero.
It looks like the Dolphins may have been worried that another team would poach Thomas from their practice squad so they signed him rather than risk losing him. Teams like Baltimore, Houston, and Dallas could all be in the market for a young QB to tutor. Thomas won't see any playing time with Miami but rather carry a clipboard behind Ryan Tannehill and Matt Moore.
