After an open date, Louisville head football coach Bobby Petrino met the media to preview his team's game with Duke but the subject of that loss in Death Valley is obviously still fresh on his mind.

Trailing 42-36, the Cardinals faced a 4th and 12 on the Clemson 14 with less than a minute to play.

Petrino said the scheme used by Clemson's defense on that play forced the Cardinals to throw.

"That's what we had to do with the look they were in," Petrino said.

"That was the only option we had."

The Cardinals were stopped on fourth down when Lamar Jackson connected with James Quick who was stopped short of a first down. But there seemed to be confusion on Quick's part on just where he needed to get to go for a first down.

"He caught the ball, he had some room to make a move, and I don't think it was an effort thing," Petrino said.

"I'm not sure that he knew exactly where he needed to go."

When asked if he was satisfied with where the yard marker was placed, Petrino didn't mince words.

"No, I wasn't," he said.

"I don't think it should be marked one place when they have the ball and one place when we have the ball," Petrino said.

He also added he has not received any feedback from the ACC on the matter.
