Green Bay Packers (7-6-1) quarterback Matt Flynn led his side to an improbable second-half comeback win over the Dallas Cowboys (7-7) on Sunday night.

Flynn, in for the injured Aaron Rodgers, threw for 299 yards and four second-half touchdowns to overturn a 26-3 half-time deficit.

Running back Eddie Lacy added 141 yards and a touchdown on 21 carries as the Packers stunned Jason Garrett and the Cowboys with a miraculous performance in Texas.

Cowboys quarterback Tony Romo tossed two late interceptions, the first giving the Packers the opportunity to score the go-ahead touchdown before his second pick sealed the Cowboys' fate in the final minute.

Romo and running back DeMarco Murray had been excellent in the first-half, while Flynn struggled to execute in Rodgers' absence.

He was impressive in the 22-21 win over the Atlanta Falcons last week, but it all went wrong in the opening two quarters in Dallas.

The Cowboys opened up a 26-3 advantage by the interval before two Packers' scores orchestrated by Flynn got them back in the game.

Trailing 36-31 in the fourth quarter, Eddie Lacy punched in a one-yard touchdown with 1:31 to go following a Romo interception to put the Packers ahead.

"It took me everything not to cry," said Packers coach Mike McCarthy. "I'm just drained. Just the sheer emotion. It was incredible."

Rodgers could return next week after missing six straight games with a broken collarbone, and with the Packers back in the playoff hunt, it could be timely.

As for Flynn, who was signed mid-way through the campaign following Rodgers' injury, the stand-in hailed one of the greatest displays of his career to date.

"Yeah, it's probably the biggest win of my career," said Flynn. "I don't anticipate being the guy going forward. We all anticipate Aaron [Rodgers] getting healthy."
