Dallas is the first team to win at least 12 games in three consecutive playoff seasons without making a conference title game.
The Packers have never lost in six trips to AT&T Stadium — including the Super Bowl over Pittsburgh during the 2010 season. They now have two playoff victories over the Cowboys after Aaron Rodgers led a 34-31 divisional win when Dallas was the NFC's top seed in 2016, Prescott's rookie year.
Those Packers let a 21-3 lead slip away. These Packers, with the four-time MVP's successor, left little doubt with a 48-16 fourth-quarter lead before two late Dallas TDs.
Facing the NFL's fifth-best defense, Green Bay matched its Super Bowl-winning team from 2010 for the most points in a playoff game. That was also on the road, a 48-21 victory at top-seeded Atlanta in the divisional round.
Doubs, who returned to the Green Bay sideline after his hospital trip before the end of last week's 17-9 home victory over Chicago that secured a playoff spot, had 102 yards at halftime. It was seven more than the second-year player's previous best.
First-half catches of 22, 26 and 39 yards helped get Love going, and the fourth-year QB finished 16 of 21 for 272 yards as the Packers scored touchdowns on seven of their first eight drives in their highest-scoring game since 2014.
One of them was set up by Prescott's first interception at the Dallas 19-yard line, from Jaire Alexander after he was questionable coming in when he sprained an ankle during the week.
A 46-yard grab by Doubs early in the second half helped finish off the Cowboys after they had scored 10 points on either side of the break. Doubs, Luke Musgrave and Dontayvion Wicks had TD catches.
Jones rushed for 118 yards, putting him over the century mark in all four career games against the Cowboys with nine touchdowns.
The crowd under the retractable roof on a frigid day in the Dallas area had already been stone-cold silenced when Prescott tried to throw a slant to top receiver CeeDee Lamb.
Savage, who went without an interception in the regular season for the first time in his five-year career, stepped in front and run untouched for a 27-0 lead with 1:50 left before halftime.
Prescott finished 41 of 60 for 403 yards, with all three of his touchdowns to tight end Jake Ferguson.
