Starting cornerback Andru Stewart was not at practice for the second straight day, but Robinson wouldn't discuss the reasons.
"It's an in-house thing," Robinson said.
Asked if Stewart would play against Eastern Michigan this week, Robinson said, "No comment."
Rudell Crim, knocked out by a hip pointer against Ole Miss, was back at practice. Robinson said, "Crim is fine." Ramon Broadway, another corner, is also slowed by an injury. Robinson said, "A decision on what to do with Ramon will come at the end of the week."
There was a shuffle between first and second team early in practice with Austin Moss, Anthony Leon and Damario Ambrose all getting some work with the first unit.
Robinson said an option at cornerback includes moving Jerell Norton back from safety.
"Jerell is perfectly willing to do that," Robinson said.
Robinson said the physical nature of the practice didn't change from earlier this year. It was full pads, a typical Wednesday.
"I thought it was really physical," he said. "We started off with our tackling sessions, then went to individual and they were both physical. I was with the secondary during inside run and so I didn't see that. But I understand that was good, physical work."
Defensive end Jake Bequette said the only difference was one period eliminated from a typical Wednesday.
"I think this is a point in the season where Coach (Bobby) Petrino takes one period off of us, the team period when we go ones vs. twos and twos against ones. We didn't have that. But we had middle drill and the run sessions. Nothing changed there. We do middle drill every day, every practice. It's still very physical."
Robinson said last week's performance wasn't acceptable from any standpoint.
"You always expect better than that," he said. "You go back and you critique it and see that we didn't get it done in most areas. We lost our technique and our focus. You look and see if you were gap sound and we weren't. You assess all areas, courage and everything."
Because of injuries, David Gordon played a lot more. Robinson said he held up well in many areas.
"He responded pretty darn well," Robinson said. "He played a lot more, probably 35 more reps than what he'd been getting. Sometimes when you aren't getting many opportunities, you add to it and they lose focus because they get fatigued. That didn't happen to him."
How has Anthony Leon progressed?
"He's getting better," Robinson said. "He's doing good. He's getting more reps this week. He seems a lot more confident. He's actually starting to talk out there and can make some checks. I'm proud of him for beginning to do that."
Gordon said it's a matter of getting more confident each week. He said it starts by just learning the proper technique.
"When I first got out here, I couldn't even back pedal or know what to do with the cone drills," Gordon said. "I couldn't do them. Now, I'm more able to do it all and I understand the technique. I'm getting comfortable."
Bequette was asked about last week's performance. What stood out after watching film?
"All the mental mistakes," he said. "You watch and you see mistakes in all areas. We were in the wrong gaps, we didn't take the right angles and the linebackers and secondary had mistakes. We all made mistakes together. It was just a bad team performance by our defense."
Was there a letdown from the Florida loss?
"I can only say about myself," he said. "I don't think there was any.
"But you can't get around that we didn't perform as well. You come here every day in practice and every game with the goal of getting better. We didn't do that last week.
"What I know is that we are on a two-game losing streak and we have to get that corrected. I don't think anyone thought we played to our ability last week. So we are highly motivated to get that corrected this week."
