MIAMI GARDENS, Fla. - On the brink of elimination from the playoff race, the Indianapolis Colts dug in.
Indy backup quarterback Matt Hasselbeck left with an injury for the fourth game in a row, and Whitehurst did just enough in relief, completing two scoring drives.
The Colts (7-8) would have been out of the playoff race with a loss, and they can still be eliminated in Week 16 if Cincinnati wins at Denver on Monday.
"We did our job today," Whitehurst said. "That's kind of what we can control. We need a little bit of help. Hopefully it goes our way, and we'll have a fun week of practice and have something to play for next week."
Miami (5-10) was eliminated two weeks ago, and a half-empty stadium reflected the sad state of the franchise. The Dolphins have lost three in a row and are 4-7 under interim coach Dan Campbell, who is likely to be replaced after the season.
Whitehurst completed a third-down pass on his first play, setting up the Colts' second touchdown for a 15-6 lead. He also directed a 10-play drive early in the fourth quarter for a field goal that made it 18-9.
"I did OK, and I got a lot help," Whitehurst said. "The defense really delivered."
Whitehurst was limping after being sacked on third down with three minutes left. But he was needed for only one more snap - out of the victory formation on the final play.
Hasselbeck said he was "not super optimistic" he would be available to play next Sunday against Tennessee.
"We'll do an MRI Monday, but I think it's just an AC sprain, which is great news," Hasselbeck said. "I had this injury to my left arm a long, long time ago, so I kind of know it's not that serious. It's just a matter of how quick."
The afternoon was rough on quarterbacks for both teams. Tannehill was sacked six times, hurt his left leg late in the game and walked with a limp in the locker room.
"It's not easy to win when quarterbacks get hit," he said. "That's something we have to fix."
"My fault," an emotional Douglas said. "I should have been locked in on that play. Bad play by me."
"He feels like it's on his shoulders, but it's not," Campbell said. "There are enough mistakes to go around, offensively and defensively. It's never one man's fault."
Landry became the first Miami player to have 100 catches in a season. He had seven receptions for 111 yards, including a sensational one-handed catch as he tumbled to the turf for a 26-yard gain.
