LOUISVILLE, Ky. (AP) — Dominique Brown's 15-yard touchdown run in the third quarter and Gerald Christian's 10-yard TD catch late in the fourth backed Louisville's big defensive performance that helped beat Miami 31-13 Monday night. The victory provided a successful Atlantic Coast Conference debut for the Cardinals and to Bobby Petrino's second coaching stint at the school. Despite the 18-point margin, Louisville showed little of the offensive efficiency expected in Petrino's return as the Cardinals outgained the Hurricanes 336-244 in a ragged game offensively for both teams.
