With or without Chad Henne, the Dolphins appeared headed for a chance at the Andrew Luck sweepstakes.
Now they have an even better shot at Luck now that their starting quarterback is out for the season. Henne opted to have shoulder surgery and was placed on the injured list on Thursday.
Miami signed Sage Rosenfels, who was released Tuesday by the New York Giants after recovering from a blood disorder that sent him to the hospital in August.
Henne separated his left shoulder when tackled on a busted play in the first quarter of Sunday's loss at San Diego. Henne may have played his last game for the Fins, because his contract expires after the season.
The new starter will be Matt Moore, who took over against the Chargers and will make his first start for the Dolphins in their next game Oct. 17 against the New York Jets.
Henne lost his past seven starts for the Dolphins, who are 0-4 with a bye this week. The injury was considered serious but he did express optimism he would quickly be back in the lineup.
The only other healthy QB with the team was rookie Pat Devlin, a member of the practice squad.
