The Ravens had four receivers who put up more than 50 yards in the one-sided game.

Manning threw for 301 yards and a touchdown to move into a second-place tie with Dan Marino on the NFL all-time list with 420 passing touchdowns, while his opposite number Cam Newton was sacked seven times and threw two interceptions.

Philadelphia Eagles quarterback Michael Vick suffered a concussion and was taken out of the game against the Dallas Cowboys early in the second quarter.
