The Green Bay Packers, Pittsburgh Steelers and Dallas Cowboys booked their places in the play-offs after victories while the New England Patriots earned a bye in the first round of the postseason. Sunday’s results meant that defending champions, the Seattle Seahawks, also secured a place in the play-offs even before their late game against NFC West rivals the Arizona Cardinals. The Packers gained their berth with a 20-3 win at the Tampa Bay Buccaneers but they will have to wait until next week to see if they can clinch the NFC North title. Green Bay will face divisional rivals the Detroit Lions in the final week of the regular season with both teams on 11-4 records ahead of the showdown. The Lions, who are also assured a play-off place, beat the Chicago Bears 20-14. Packers quarterback Aaron Rodgers completed 31 of 40 passes for 318 yards and a touchdown and running back Eddie Lacy rushed for 99 yards including a 44-yard touchdown run. The Steelers, six-time Super Bowl winners, have been absent from the postseason for the past two seasons but Mike Tomlin’s team ensured they will be in the mix this year thanks to a 20-12 win over the Kansas City Chiefs. Quarterback Ben Roethlisberger directed the Steelers (10-5) to their third consecutive win, passing for 220 yards and a touchdown. The most emphatic statement came from the Dallas Cowboys who crushed the play-off-bound Indianapolis Colts 42-7. With the win the Cowboys finish top of the NFC East for the first time since 2009. With another impressive performance Cowboys quarterback Tony Romo surpassed Troy Aikman to become the franchise’s all-time leader in passing yards. Romo set the record on a touchdown pass to tight end Jason Witten which put the Cowboys up 35-0. He now has 32,971 yards passing in eight full seasons. Aikman, who retired in 2000, had 32,942 yards in his one-team, 11-year career. Romo completed 18 of 20 passes for 218 yards and four touchdowns before given a rest in the fourth quarter.
