Tannehill was eventually named the team's regular season starter heading in the second preseason game against the Carolina Panthers.
[3] The Dolphins opened the regular season with a disappointing 30–10 loss against the Houston Texans, but a week later ended up with an impressive 35–13 win over the Oakland Raiders.
Following the win, the Dolphins lost two close overtime games against the Arizona Cardinals and division rival New York Jets.
[4] Despite getting an extension through 2013 in the early 2011 off-season,[5] head coach Tony Sparano was fired by the team after 13 disappointing games into the 2011 season with a 4–9 record.
[8] Sherman, who was fired by Texas A&M earlier this year after posted a 25–25 record in his four seasons, gave Philbin his first NFL job when he served as head coach for the Green Bay Packers.
At the time of signing with the Dolphins, Sherman was also a finalist for the vacant head coaching job for the Tampa Bay Buccaneers.
After an unpromising 13–18 record as a starter, the Miami Dolphins decided not to renew the contract of quarterback Chad Henne.
[10][11] The Dolphins' first major transaction of the off-season was the trade of 2011 Pro Bowl wide receiver Brandon Marshall.
The Dolphins were one of the teams who've considered signing the long-time Colts quarterback, along with the Tennessee Titans, Arizona Cardinals, and Seattle Seahawks.
However, speculation was quickly suppressed when Wayne re-signed with the Indianapolis Colts, leaving the Dolphins without a number one wide receiver entering the draft.
[12] On March 14, 2012, the Dolphins re-signed defensive tackle Paul Soliai, to a two-year deal worth $12 million.
[15] During the season, the Dolphins extended the contract of punter Brandon Fields, to four years worth $13 million, on August 4, 2012.
[19] The transaction saved the Dolphins $4.3 million in cap space, and allowed two-year safety Reshad Jones to move to the position.
[22] After struggling to adapt to new defensive coordinator Kevin Coyle's system, the Dolphins traded former first-round pick and cornerback Vontae Davis on August 24, 2012.
The Dolphins received the ball on their own 42-yard line after a missed field goal by Houston kicker Shayne Graham.
After a Reggie Bush recovered fumble on 3rd down on the Houston 14-yard line the Dolphins kicker Dan Carpenter attempted and successfully executed a 39-yard field goal with (3:19) left in the first quarter.
Following the score the Dolphins moved quickly to the Houston side of the field after a 10-yard rush by Reggie Bush and 32-yard pass to running back Daniel Thomas.
On the first play following the Houston kickoff quarterback Tannehill again had his pass deflected by a defensive lineman, but instead was intercepted by Kareem Jackson.
The turnover was shortly followed by a 14-yard pass touchdown from Houston quarterback Matt Schaub to receiver Andre Johnson at the (0:12) mark.
But for the remainder of the game the Dolphins offense failed to produce any scores, but held the Texans defense to two Shayne Graham field goals: 40 and 19 yards, respectively.
Two possessions later at the (3:28) mark in the first quarter, Oakland quarterback Carson Palmer threw a 64-yard touchdown to Mike Goodson tying the game.
However, Oakland managed to get the ball back with (3:33) left in the quarter and orchestrated a drive that ended with a Sebastian Janikowski 25-yard field goal.
On the second possession of the half the Dolphins drove the ball down field and allowed Reggie Bush to rush for a 25-yard touchdown.
