Mallett sustained a bruise to his left shoulder against Ole Miss, missing the last part of that game. Petrino said it was a hit to the "scapula" and caused the muscle in his shoulder to lose strength.
"It loosened up pretty quickly Tuesday and he got his velocity back almost immediately," Petrino said. "You could see it in the early part of the practice, during some of our route drills. He got his confidence back and he had a good week of work."
Petrino said the practice snaps were handled exactly the same as previous weeks between Mallett and backup Tyler Wilson, despite Wilson's impressive work in the last two games. It was obvious from listening to Petrino that Mallett would continue to start.
Childs also sustained an ankle injury against Vandy. He missed Tuesday's practice, but came back to finish all of the Wednesday workout.
"Greg is good," Petrino said. "He was able to finish the (Wednesday) workout, which was a surprise. I thought he looked good out there (Thursday)."
Dede Jones was suspended this week after an arrest for a marijuana possession charge a little after midnight Tuesday. Petrino declined to discuss the length of the suspension Thursday, relying on a familiar line when quizzed on injuries, "Let's talk about those who are going to play."
The Hogs have five available players for the two inside defensive tackle spots. Along with Askew, they can rotate Byran Jones, Patrick Jones, Zach Stadther and Alfred Davis. All have played big roles for the Hogs at times over the last two seasons.
The Razorback coach said the wide receivers have had a good week and solid depth is there at that spot, too.
"Julian Horton has had a very good week," Petrino said. "Javontee Herndon has done real well this week. Maudrecus Humphrey is fast and is in the rotation at the inside receiver position."
Petrino called it a good week of practice.
"We've had good focus and no signs of a letdown," he said. "Our players are motivated and our coaches have a good plan."
Petrino was asked if he realized that the Hogs are the last team in the SEC to play in their campus stadium in back-to-back weeks?
"No, we found another reason to be mad," he smiled.
