The Dolphins could have closed out the victory after Seattle kicked off deep, but instead went three-and-out. And that three-and-out came with another big scare. Chad Pennington scrambled on third down and the ball came loose at the end of the play, with Tennessee recovering the fumble inside the Miami 30-yard line.
The Dolphins challenged the ruling, and the call was reversed, giving Miami the opportunity to punt on fourth down.
After Vonnie Holliday sacked Wallace on first down, the Seahawks gained 10, 10 and 11 yards to move to the Dolphins 49, but the drive ended with a spike and three incompletions.
This was a game that began with two dominating drives by the Dolphins, even after Ted Ginn Jr.'s return for a touchdown on the opening kickoff was wiped out by a debatable holding penalty.
Undeterred, the Dolphins marched 90 yards, the score coming on a 39-yard pass from Pennington to Ginn off a flea-flicker.
The next time the Dolphins got the ball, they marched 76 yards, the second touchdown coming on a 51-yard run by Ricky Williams with the Dolphins in the Wildcat formation.
But the offense starting struggling from that point on, while the Seahawks scored 13 consecutive points.
The Dolphins put together another great scoring drive, this one consuming most of the fourth quarter. The 16-play, 79-yard drive was capped by Ronnie Brown's 16-yard touchdown, again from the Wildcat formation, and made the score 21-13.
That set the stage for the wild finish.
Even though it was closer than expected, this still was a big victory for the Dolphins, who find themselves at 5-4, their first winning mark since the end of the 2005 season.
