Following a 22-21 comeback win against the Atlanta Falcons, the Packers travelled to AT&T Stadium, the site of Super Bowl XLV, to take on the 7-6 Dallas Cowboys. Matt Flynn made his 3rd start as Aaron Rodgers was deemed not ready to return from a broken collarbone. The two teams traded field goals with their first possessions, but Dallas went on to score 23 unanswered points to take a 26-3 lead at halftime. The 2nd half began with a bang as Eddie Lacy rushed to Dallas' 20 yd. line for a 60-yard gain. Three plays later, Matt Flynn connected with Jordy Nelson for a 13-yard TD. Tony Romo and the Cowboys offense responded with a field goal to make it 10-29 with over 6 minutes left in the 3rd quarter. On the Packers next drive, Matt Flynn converted two 3rd downs with 22- and 21-yard passes to Andrew Quarless and Jordy Nelson, respectively. Flynn capped the drive with a 3-yard TD pass to Quarless to pull within 12 points. After two incompletions, Tony Romo was sacked by Clay Matthews and Dallas was forced to punt before the end of the 3rd quarter. A good punt return by Micah Hyde gave the Packers offense good field position at the Dallas 22. Early in the 4th quarter, James Starks scored on an 11-yard screen pass and made it 24-29. Dallas countered with a 5-yard TD pass to Dez Bryant to increase their lead back to 12, but Green Bay responded with a 3-yard TD pass to James Jones to make it 31-36. Dallas' next drive ended with an interception by Sam Shields at midfield with 2:50 remaining. The Packers offense led a drive that was capped off by Eddie Lacy's 1-yard TD that took the lead 37-36 with 1:34 remaining. After the failed 2-point attempt, Dallas attempted a field goal drive, but Tony Romo's pass was intercepted by Tramon Williams to seal the 23-point comeback win for the Packers.
