Two of the most historic franchises in the NFL will face off Sunday night when the Dallas Cowboys travel to Santa Clara, California to play the San Francisco 49ers. Both teams entered the season as Super Bowl contenders, but so far they have looked anything but.

Coming home from a 47-9 drubbing of the Detroit Lions, Dallas has seen their once-vaunted defense falter all season. San Francisco has been inconsistent for seven weeks, partly due to the many injuries to star players. The 49ers have lost two of their last three games.
