DAVIE, Fla. (August 20, 2012) -- Rookie quarterback Ryan Tannehill has won the Miami Dolphins' starting job.

Coach Joe Philbin announced following practice Monday that Tannehill will start the Dolphins' opener Sept. 9 at Houston.

Tannehill beat out Matt Moore, who finished last year as Miami's starter. Training camp began with a three-way competition for the job, but veteran David Garrard fell out of contention when he underwent minor knee surgery Aug. 11.

Tannehill, who played at Texas A&M, was drafted with the eighth overall pick, which made him the first quarterback taken in the opening round by the Dolphins since Dan Marino in 1983.

He'll be the 17th starting quarterback for Miami since Marino retired following the 1999 season, the most in the NFL.
