MIAMI GARDENS, Fla. -- With players from the 1972 Dolphins watching on the 40th anniversary of the NFL's only perfect season, Miami scored 21 unanswered points to defeat the Jacksonville Jaguars 24-3 Sunday.
Pulling away from a 3-3 first-quarter tie, the Dolphins (6-8) earned their second win in the past seven games. The Jaguars (2-12) lost for the 10th time in the past 11 games.
Miami rookie quarterback Ryan Tannehill displayed the effective form he possessed earlier in the season, completing 22 of 28 passes for 220 yards and two touchdowns and a 123.2 rating. He also ran for 52 yards on eight carries, and he passed for a two-point conversion.
Dan Carpenter added field goals 53, 30 and 31 yards for the Dolphins.
Jacksonville's only points came on a 37-yard Josh Scobee field goal.
The Dolphins' running game produced 180 yards, including 104 yards on 21 carries by Reggie Bush.
The game turned early in the second quarter on an illegal-substitution penalty that wiped out a 20-yard Jacksonville touchdown pass from Chad Henne to Justin Blackmon. Henne, the former Miami starter, threw for 221 yards on 18-of-34 passing.
Jaguars offensive guard Guy Whimper, who reported as an eligible receiver previously, entered the game but did not report as an eligible receiver.
The Dolphins held when they stopped a Henne run on fourth-and-1 from the 11. It was the first of three times that the Miami defense stopped Jacksonville on fourth down in the red zone.
Tannehill then drove the Dolphins 89 yards in 14 plays. He threw a 4-yard scoring pass to Jovorskie Lane to give Miami a 10-3 halftime lead.
Tannehill converted three third downs on the drive, one on a 15-yard pass to Marcus Thigpen on third-and-6 from the Miami 13-yard line, another on an 11-yard run on third-and-1 from the Miami 37, and the final one on a pass to Rishard Matthews when interference was called on Rashean Mathis.
Miami outscored the Jaguars 6-0 in the third quarter, running 20 plays to Jacksonville's 9. The Dolphins had possession for 12:30 of the quarter.
On their first possession after halftime, the Dolphins drove to the Jaguars' 4, but a fake field goal went awry when holder Brandon Fields was forced to throw over the head of a covered Anthony Fasano.
Fasano was initially open, and only the quick recognition and reaction of cornerback Mike Harris prevented a completion and possible touchdown.
Following a Jacksonville punt, Bush broke a 53-yard run that led to a 30-yard Carpenter field goal.
Carpenter added a 31-yard field goal with 1:01 left in third quarter to expand the lead to 16-3. The 64-yard drive included a 30-yard Tannehill run and two completions to Brian Hartline covering a total of 26 yards.
The Jaguars drove to the Dolphins' 15 but came away with no points when Jason Trusnik stopped a Montell Owens run on fourth-and-1.
Miami proceeded to drive 85 yards in 14 plays using 9:01, and Tannehill threw 2 yards to Fasano for the touchdown with 3:12 left in the game. He then threw to Fasano for the two-point conversion and a 24-3 lead.
The Jaguars used a 38-yard completion to Blackmon on third-and-3 from their 27 to set up Scobee's 37-yard field goal on the game's first possession. They would not score again.
The Dolphins answered with a 53-yard field goal by Carpenter with 6:26 left in the quarter. Tannehill had completions of 13 yards to Marlon Moore and 14 yards to Fasaano to highlight a 43-yard drive.
