Quarterback Aaron Rodgers connected with wide receiver Greg Jennings on a quick slant on the first play of the Packers' next possession, and Jennings put a nifty move on cornerback Anthony Henry and took it down the left sideline for 26 yards. Rodgers was sacked on third down deep in Dallas territory and the Packers settled for a 36-yard Mason Crosby field goal to even the score at 3-3.
Dallas drove inside the Green Bay 20 on their next possession, but quarterback Tony Romo's pass on third down intended for tight end Jason Witten was picked off by safety Nick Collins and returned 61 yards to the Cowboys' 43.
After the turnover, Rodgers made a nice play by stepping up in the pocket to avoid a sack by nose tackle Jay Ratliff and connected with Jennings for 14 yards. Crosby kicked a 38-yarder to give Green Bay a 6-3 lead.
Rodgers has completed 8-of-13 passes for 94 yards in the first half, and Jennings has five receptions for 80 yards.
