ATLANTA -- Matt Ryan came up with two words to describe his performance Sunday night.
"Good enough," he said.
It's a familiar summary for the 2012 Atlanta Falcons, who just keep winning -- even when they make a couple mistakes.
Michael Turner had a tiebreaking 3-yard touchdown run in the fourth quarter, Matt Bryant kicked four field goals and the Falcons beat the Dallas Cowboys 19-13 to extend their run as the NFL's only unbeaten team.

"I think, at the end of the day, it's a league that's based on wins and losses ,and tonight was a solid effort by this team and we did what we needed to do to come out with a win," Ryan said.
Turner had 20 carries for 102 yards and Ryan had a season-high 342 yards passing for the Falcons (8-0), who took their first lead with 14:16 left in the game.
"We have a very good football team," coach Mike Smith said. "It says a lot about the resolve because there is going to be ebbs and flows in a football game, and there were a lot tonight. We did a nice job staying focused."
Tony Romo completed 25 of 35 passes for 321 yards for the Cowboys (3-5), who have dropped four of their past five games. They were held to 65 yards rushing, including 39 yards on nine carries by Felix Jones.
"There's a reason they're undefeated halfway through the season," Dallas coach Jason Garrett said. "This is a challenging place to play at. I thought we did some good things in the ballgame. They did more good things. We didn't do enough to win this game in all three phases of our football team."
The Cowboys trailed 16-6 before Romo tried to put together a comeback. He completed all six of his attempts on a big drive that ended with a 21-yard TD strike to Kevin Ogletree.
The Falcons then worked the clock, holding the ball for 5 minutes, 4 seconds, leaving only 17 seconds after Bryant's 32-yard field goal.
The Cowboys burned all their timeouts as Ryan kept the Falcons' offense on the field in the crucial time-consuming drive. Ryan passed to Jacquizz Rodgers for 31 yards and 11 yards on third-down plays. A defensive holding call against cornerback Orlando Scandrick on another third down prolonged the possession.
Finally, the Cowboys stopped Turner on a third-down run at the Dallas 14.
Romo never attempted a deep pass, though he had only 17 seconds to cover 80 yards. He found Jason Witten for passes of 7 and 11 yards, leaving 9 seconds. He passed to Felix Jones for 8 yards, leaving time for one play from the Cowboys 40.
Romo scrambled before passing to Jones, who was dropped near the Atlanta 22 to end the game.
"I think any time you're in that situation you obviously want to get the ball back with a chance, and it's tough," Romo said. "That's why they're a good football team. They're tough to beat at home. They proved it when they were able to run the clock out at the end."
There also is a new Dallas leader for career receptions. With seven catches for 51 yards, Witten has 754 for his career, passing Michael Irvin's record of 750.
Miles Austin led the Cowboys with seven catches for 76 yards.
Cowboys owner Jerry Jones said he was "extremely, extremely" disappointed.
"We certainly didn't plan to end up here at 3-5 halfway through the season," Jones said. "We've got some tough ballgames. We've got half our season left."
For three quarters, it was a kicking contest -- and a pretty shaky one, too.
Bryant kicked field goals of 45 and 46 yards in the second quarter for Atlanta's only points before Turner's score. Bryant also missed from 43 and 37 yards, wide right each time.
"Tonight was not a very good day as far as overall body of work," said Bryant, who made 27 of 29 attempts in 2011 and was 16 for 17 this season before Sunday night's game. "It was just one of those days where you have to have a short memory and get ready for the next game."
Dan Bailey's field goals from 23 and 32 yards were the Cowboys' only points in the first half. He missed from 54 yards.
Ryan was sacked three times and faced constant pressure.
Ryan's 48-yard pass to Jones set up Bryant's 36-yard field goal in the fourth quarter, pushing the lead to 16-6.
