"I want to see us be physical," Petrino said after practice Thursday. "That's what we've done (against South Carolina) the last couple of years. We've gone out and played hard and stuck together.
"We have to stop the run and hit that young back. We have to generate some running game."
It's No. 7 Arkansas against No. 9 South Carolina. Petrino said his players have acted like it's a big game.
"Like I've said before, this is an easy week," Petrino said, noting the excitement in preparations. "We've had great focus and concentration."
Petrino was asked questions that revealed the defensive end depth. Junior end Tenarius Wright, trying to come back from a broken arm against Alabama, is still not ready to play. True freshman Lonnie Gosha has left the team.
"Tank (Wright) is not ready yet," Petrino said. "He's closer, but he's not ready this week."
Gosha has struggled to get playing time as another true freshman has emerged at defensive end. Trey Flowers has settled in as the starter with Wright on the mend. Petrino was asked about Gosha and only said, "He's quit the team."
On Wednesday, defensive coordinator Willy Robinson said the team had changed up some things in practice in hopes of getting a better performance after two lackluster starts. He declined to comment on specifics. Petrino seemed to downlplay any changes.
"We haven't done anything different," he said. "Our schedule is exactly what we have done this time of year. It's the exact same amount of time on inside run.
"I'm excited about the kind of leadership we have been getting from our defensive front. Byran Jones, Dede Jones and Robert Thomas are helping with our leadership."
Petrino was asked how Marquel Wade has handled a tough week. There have been criticism from the national media following the flagrant personal foul and ejection at Vanderbilt, then a one-game suspension from the SEC office.
"It's been hard on him," Petrino said. "He was out there competing, trying to make a play. He got there early, but he thought the player had the ball. He thought he made a big play. Our discussions have been about how he handled himself after the play."
