Ryan Tannehill will start at quarterback for the Miami Dolphins.
It hasn't been officially announced, nor implied, and Tannehill might not even start tonight's game against the Buccaneers.
But come September 9th against the Houston Texans, Tannehill will be the starting quarterback—unless Matt Moore has an out-of-this-world performance during the preseason and for the remainder of training camp.
This is because the favorite for the starting quarterback job, David Garrard, underwent knee surgery today (according to Sean Jensen of the Chicago Sun-Times, via Pro Football Talk). According to Jay Glazer, Garrard is expected to be out for two to four weeks—effectively the entire preseason.
Garrard's injury opens up the door for Tannehill to take the starting job.
Tannehill has already been the best quarterback in camp for Miami since he reported. The only reason Garrard looked like he was going to get the starting job was because he's been close enough during camp and has the experience Tannehill lacks. Another reason is the Dolphins seemed to intend for Tannehill to sit, watch and learn for a little while.
However, that option looks like it's off the table.
Tannehill already has a leg up on Moore in the quarterback race, and if training camp has been any indication, he also gives Miami a better chance to win than Moore.
Garrard still expects to play for the Dolphins when he comes back. But after missing training camp, and with the most important Dolphins draft pick since Dan Marino already impressing many—both within and outside of the organization—his only chance will likely be if he's willing to hold a clipboard this season.
