The Facts: The Dolphins signed Losman on Tuesday, placing Sage Rosenfels on the Reserve/Non-Football Illness List according to the South Florida Sun-Sentinel.
Diehards Line:Losman, a former first-round draft pick, played with the Bills from 2004-08, starting 33 games. Rosenfels released a statement about the abrupt end to his football season: "I am thankful for the opportunity the Dolphins gave me to come here and play, and I was looking forward to contributing to the team when I signed. When I first joined the Dolphins, all tests showed that I was healthy and ready to go. But after practicing for a few weeks, especially in the heat, some new indications made it obvious that I need to rest and allow my body to regain all requisite strength. ..." Meanwhile, ESPN's Adam Schefter notes that starting QB Matt Moore has sore ribs after Sunday's loss to the Broncos. It's a situation worth watching.
