MIAMI -- The Miami Dolphins' revolving door at quarterback spun anew Tuesday, when the team placed quarterback Sage Rosenfels on the reserve-non-football illness list and signed J.P. Losman, who last completed a pass in 2008.

A blood disorder sent Rosenfels to the hospital in August, and he said in a statement that he hasn't fully recovered.

"When I first joined the Dolphins, all tests showed that I was healthy and ready to go," Rosenfels said. "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."

Rosenfels joined the team Oct. 6 after Chad Henne suffered a season-ending shoulder injury. The only other quarterback on the roster is Matt Moore, who this month became Miami's 16th starter at QB since Dan Marino retired.

Losman, a first-round draft choice in 2004, started 33 games in five seasons with the Bills, with 33 touchdown passes and 34 interceptions. He spent part of the 2010 season with the Seattle Seahawks but didn't play.

The Dolphins (0-6) play on the road Sunday against the New York Giants (4-2).
