ARLINGTON, Texas -- Quarterbacks ruled Sunday afternoon at AT&T Stadium, as Peyton Manning and Tony Romo were locked in an epic duel.
To the surprise of pretty much no one, Manning won.
The future Hall of Famer led another fourth-quarter comeback in a wild back-and-forth affair that ended with the undefeated Denver Broncos escaping with a 51-48 victory over the Dallas Cowboys.
The Broncos, down 48-41, scored the game's last 10 points to improve to 5-0. Danny Trevathan set up Matt Prater's game-winning chip-shot field goal, intercepting Romo with less than two minutes left.
Manning passed for 414 yards and four scores. He also ran for another, his first in five years. Six different receivers had at least four catches. Knowshon Moreno ran for 93 yards.
"We were kind of in a storm early, (down) 14-nothing on the road," said Manning, who owns the NFL record with 39 fourth-quarter comebacks. "That place was rocking and I thought we did a good job of digging ourselves out."
Romo threw for five touchdowns and 506 yards, breaking the franchise single-game record. He commandeered a second-half rally that overcame an 11-point deficit with four scoring passes.
"Tony was awesome today," Manning said.
Dez Bryant, Terrance Williams and Jason Witten combined for 413 yards and four touchdowns for Dallas. The Cowboys had a season-high 522 yards of offense.
"We were moving the ball with control," Witten said. "They didn't have a whole lot of answers for us. We had some big plays that we hadn't had most of the season.
"You leave this game, obviously you're crushed, but offensively this needs to be the standard to which we play to give ourselves a chance to win."
Dallas had the chance with the ball, but Romo's only mistake of the game proved deadly.
"The kid made a good play," Romo said of Trevathan's diving pick. "I just didn't get as much on it."
The Cowboys (2-3) rallied after falling behind 38-27, taking advantage of Manning's first interception of the season late in the third quarter. Romo touchdown passes to Bryant and Williams gave Dallas its first lead since the first half at 41-38.
"That's the best football team we've played," Dallas coach Jason Garrett said. "So we stepped up to the challenge."
The start couldn't have gone any better for the Cowboys. Dallas took a 14-0 lead with two touchdown drives sandwiched around a Denver turnover.
Manning and the Broncos weren't fazed. Denver found its bearings and was up 28-20 going into halftime. Manning accounted for all four touchdowns.
"This was our best character victory as far as coming from behind," Broncos coach John Fox said.
The Cowboys went 79 yards with ease on their first possession, chewing up nearly seven minutes. Romo was perfect on the drive, with long completions to Williams and Witten, setting up a 2-yard touchdown toss to Bryant in the back of the end zone.
The Broncos turned it over the first time they touched the ball, with Eric Decker fumbling the ball away on the Denver 45.
