Philadelphia at Dallas: This rivalry has many memorable moments, including Wilbert Montgomery shredding the Cowboys for 194 yards in the 1981 NFC title game, Emmitt Smith running for 114 yards in the Cowboys' 34-10 dismantling of Philadelphia in the 1993 conference semifinals, and Eagles fans cheering an injured Michael Irvin as he lay motionless on the Veterans Stadium turf with a career-threatening neck injury in 1999.

New England at Atlanta: The Patriots are 2-2 after a 41-17 loss to the Chargers at home, where New England had not lost since 2002. Now the Super Bowl champions -- minus safety Rodney Harrison, who is out for the season with a knee injury -- must face a Falcons offense that has averaged 27 points over the past two games and even moved the ball effectively when starting quarterback Michael Vick left yesterday's game in the second quarter with a sprained knee.

Pittsburgh at San Diego: The Steelers figured to be well rested after their bye week, and they'll need all their weapons at full strength when they travel across country to play the surging Chargers. San Diego picked apart the Patriots' defense yesterday with a mix of run and pass. Tailback LaDainian Tomlinson rushed for 134 yards and two touchdowns, and quarterback Drew Brees passed for 248 yards and two touchdowns.
