And while U of L's complete focus hasn't yet turned to their September 4 season-opener against UK, Petrino admitted after practice that his squad has already begun preparations behind closed doors this week for the Wildcats.
"After Saturday we'll settle in and really start focusing in on Kentucky, although we did a lot this week," Petrino said.
The Cardinals looked sharp last week when practice was open to fans and media, and Petrino said Wednesday that he's pleased – for the most part – with what he's seen on the practice field.

Junior Brinson Harley and redshirt freshman Maurice Mitchell are battling to enter the mix at tackle, as is true freshman Earl Heyman, who has been working overtime after practice to hasten his move up the depth chart.
"Really you need three corners," he said. "Those three guys will play in our nickel package.
