"We don't have to give out an injury report until Jet week," said Sparano, whose team doesn't play again until a Monday night game at New York on Oct. 17. "So right now I'm not going to talk about that."
He might not have needed to say anything, given the way Henne appeared before practice. The quarterback walked onto the practice field wearing a white jersey, shorts and a baseball hat. His left arm hung noticeably limp at his side, and he didn't move it or bend it at the elbow.
Matt Moore, the Dolphins' backup quarterback who entered the game Sunday, worked with the first team in practice Tuesday. If Henne is to miss significant time, the Dolphins would need to add a quarterback to their 53-man roster.
David Garrard, whom the Jaguars released before the start of the season, could be an option. The Dolphins might also consider promoting Pat Devlin, an undrafted rookie from the University of Delaware, from the practice squad.
Devlin said Tuesday he hadn't been informed about whether he could be promoted.
"It'd be a great opportunity," he said. "I know Matt knows he's only a play away. That showed this weekend. So I know he's ready to go, and any backup quarterback needs to be that same way."
