LOUISVILLE, Ky. -- Louisville football is entering camp with some big questions unanswered.

Head coach Bobby Petrino says he's happy with how the team ended spring practice but says they will need to tackle the challenge of replacing Teddy Bridgewater in fall camp. Petrino says he's also looking to strengthen the offensive line and find a good fit for the safety position.

He says the team has been in the weight room all summer and he's looking forward to seeing their strength tests in the coming weeks.

The Cards open the season at home on September 1 with a nationally televised game against Miami.
