Chad Henne hurt himself in a most unfortunate way against San Diego in Week 4 (a blown draw play that resulted in him diving up the middle for a yard or two) and reports started circulating that Henne suffered a separated shoulder.

Those reports are true, and the Dolphins announced Thursday that they placed Henne on injured reserve, thus ending his season. To make up for Henne's loss, the Dolphins have signed veteran Sage Rosenfels.

"Congrats to Sage Rosenfels who just signed with the Miami Dolphins," Rosenfels agent, Rick Smith, tweeted Thursday.

Rosenfels was on the Giants injured reserve with a blood illness of sorts, and hasn't thrown a regular-season pass since 2008. Which means that, yes, Matt Moore will remain the starter in Miami.

That the Dolphins were able to get Rosenfels to pass his physical is good news -- they were turned down by some not-so-elite quarterbacks like Jake Delhomme, David Garrard, Trent Edwards and Brodie Croyle.

None were interested, but the NFL Network's Jason LaCanfora notes that it may have simply been a financial issue -- Miami only wanted to offer Garrard $600,000 with no money guaranteed.

So, yeah, the Dolphins at 0-4 find themselves in a pretty bad position without their starting quarterback. Although not having a good signal caller under center isn't exactly new for them -- they've been missing a quarterback even since Dan Marino left.

"I can only look at the last three, four years," head coach Tony Sparano said Wednesday. "I don’t know about the last decade or anything like that. I just know about the last couple two, three years. We’ve had a couple quarterbacks in there. Obviously [Chad] Pennington, [Chad] Henne, Pat White, Tyler [Thigpen] ... we got a few different guys. As far as starters go it’s been Pennington and Henne. For us it’s been pretty consistent."

Sparano pointed out that he's been on the winless end of things this deep into the season before (when he worked for Marty Schottenheimer in Washington), but he wasn't the guy with his neck firmly on the chopping block.

Now he is, and without his starting quarterback, it's hard to imagine how he'll survive an already tepid start.
