Tannehill completed passes of 15, 24 and 13 yards in a drive that led to Daniel Thomas' 1-yard touchdown run that put the Dolphins ahead to stay 7-6 late in the first half. He avoided the rush and completed a 28-yard pass that set up Reggie Bush's 13-yard touchdown run to start the third quarter.
It could have been even easier for the Dolphins. Fullback Jorvorskie Lane fumbled on a carry from the Cincinnati 11 in the first half.
Still, it was more than enough for a defense that contained the Dalton-to-Green passing combo. Green finished with nine catches for 65 yards, including a 2-yard touchdown.
Cincinnati had to settle for a pair of field goals in the first half, when Miami's defense held on a first-and-goal from the 4-yard line.
"The offense didn't play well across the board," Dalton said. "It's tough sitting here where we are. We had our chances, but we couldn't get it done."
Tackle Randy Starks reached up and picked off Dalton's pass early in the second half, a two-handed grab as the ball reached the line. The interception set up the drive that ended in Bush's 13-yard touchdown run.
