Dallas Cowboys quarterback Tony Romo left Sunday's game against the San Francisco 49ers with a rib injury.

Near the end of the first half, Rome was blindsided on a pass attempt and when play resumed for the second half, he did not take the field.

Romo went 8-for-17 for 144 yards and a touchdown in his half of play. Jon Kitna replaced him under center for the second half.
