ARLINGTON, Texas -- If this was Matt Flynn's last start in place of Aaron Rodgers, it was quite a memorable one.

Flynn threw four touchdown passes in the second half, Eddie Lacy had the winning score on a 1-yard plunge after an interception by Tony Romo gave them one more chance, and the Green Bay Packers matched the biggest comeback in franchise history in a 37-36 win over the Dallas Cowboys on Sunday.

Romo tossed two interceptions in the final 3 minutes, the first one giving Green Bay a chance for the go-ahead score with the Cowboys in position to run out the clock with a 36-31 lead.

Lacy scored with 1:31 to go for Green Bay's first lead since the first quarter and after the Packers trailed 26-3 at halftime.

"It took me everything not to cry," said Packers coach Mike McCarthy, whose team won its second straight without Rodgers after going winless in the first five, including the Chicago game when the star QB got hurt. "I'm just drained. Just the sheer emotion. It was incredible."

"Most guys would pack it in -- 'Guys, it's not our season. Let's go home and get ready for next year,' " said Green Bay cornerback Tramon Williams, who had an interception overturned on review before a game-clinching pick that was ruled incomplete and reversed on replay. "It's not that vibe here."

Playing on the same field where Rodgers was the MVP when they won the 2011 Super Bowl, the Packers matched the 1982 team in a September game against the Los Angeles Rams for the largest rally.

The Packers (7-6-1) kept their playoff hopes alive with Rodgers possibly returning next weekend. He was close to medical clearance, but missed his sixth straight game with a broken collarbone. He was wearing a headset on Green Bay's sideline. There will be no quarterback controversy.

"Yeah, it's probably the biggest win of my career,'' said Flynn, who has won two straight starts after the Packers were winless for five straight without Rodgers, including the Chicago game when he broke his left collarbone. The epic rally fueled by Flynn -- and helped along by Romo -- didn't change anything about the quarterback situation with the Packers (7-6-1) still in playoff contention heading into a home game against Pittsburgh.

"I don't anticipate being the guy going forward,'' said Flynn, who was released twice this year before the Packers picked him up after Rodgers got hurt. "We all anticipate Aaron getting healthy."

The vibe in Dallas could be negative for a while, with Dez Bryant walking off the field before the game ended and refusing to talk to reporters in the locker room, simply shaking his head at them after finishing with 153 yards and a touchdown.

After the game, Bryant took to Twitter to explain his early exit.

I walked back to the locker room because I was emotional...it had nothing to do with my teammates we had it... We fought and didn't finish — Dez Bryant (@DezBryant) December 16, 2013

"This is one of the hardest losses that I've experienced," Cowboys owner Jerry Jones said. "That's a shame that we've lost that ballgame."

The Cowboys (7-7) blew a great chance to pull even with Philadelphia in the NFC East but still control their playoff fate. They finish with Washington and the Eagles.
