Multiple outlets have confirmed that Dolphins quarterback Chad Henne will miss the rest of the season after opting for surgery on his left (non-throwing) shoulder. Henne suffered the injury early in last week’s game against the San Diego Chargers, when he tried to scramble on a broken play and had his shoulder slammed to the ground.  After Henne initially indicated he’d be ready to play after the bye week, he consulted two doctors, both of whom reportedly advised him to undergo the season-ending surgery.

Henne finishes the year with a 4:4 touchdown-to-interception ratio, a career-best 79.0 QB rating, and a career-worst 57.1% completion percentage. Considering he’ll be free agent after the season, it’s possible that he’s played his final game as a Dolphin.

Matt Moore, who threw for 167 yards and a pick in relief of Henne last week, will almost surely start against the New York Jets next week (we do have a few tickets available, if you’re wondering). Since the only other QB on the roster is practice squad rookie Pat Devlin, Miami will sign another veteran back-up in the coming days; according to reports, the team has reached out to David Garrard, Jake Delhomme, and Sage Rosenfels, and worked out Brodie Croyle and Trent Edwards.

While Garrard, a 2009 Pro Bowler who was unexpectedly released by the Jacksonville Jaguars, inspires the most confidence from that list, the Dolphins have thus far balked at giving him a guaranteed contract and a starting job.  Rosenfels spent the first four years of his career with the Dolphins — throwing for 278 total yards, one TD and five picks in two starts — and his career “highlight” is this ridiculous helicopter hurdle.  I’d rather not even think rooting for Delhomme, who’s thrown 10 TDs and 25 INTs in 16 games over the last two years.

Meanwhile, Moore, like Henne, has been frustratingly inconsistent during his four-year career, throwing 16 TDs and 18 interceptions in 13 starts. After throwing eight TDs without a pick over the final four games of 2009 — including 299 passing yards and three TDs in a win over the 11-2 Minnesotta Vikings — Moore sported a 5:10 TD-to-INT ratio and lost his starting job to rookie Jimmy Clausen last season.  Perhaps Moore can still develop into a serviceable starter, but it’s looking more and more like Dolphins may be in the thick of the Andrew Luck sweepstakes.

Update: The Dolphins did indeed bring back the 33-year-old Rosenfels on a one-year contract, after also working out the likes of Kellen Clemens, Charlie Frye, J.P. Losman, and Jim Sorgi. Hey, at least it wasn’t Delhomme.
