In fact, when told there was an earthquake, he thought maybe it happened just as Tyler Wilson attempted a pass that Cobi Hamilton dropped in the end zone just before halftime.
"That's when it must have happened because Cobi just doesn't drop balls," Petrino said. "I thought, 'Are you kidding me -- Cobi doesn't drop passes.' "
Petrino was pleased with the performance against Carolina.
"Going in, we wanted to play physical, play fast and with energy," he said. "I thought we did that well.
"Our offense had rhythm. Obviously, we left some points out there, but I was happy with all three phases of our play."
There were a lot of questions about the BCS rankings and the change this week that dropped Arkansas from No. 7 to No. 8.
"I can't figure it out," Petrino said. "I'll let you guys figure it out."
Petrino was asked if the team needed more style points to influence the BCS poll.
"What we do is really focus on Tennessee," Petrino said. "What we do is really focus on practice. We all know that what we have to do is beat Tennessee this week.
"What we want is for the state of Arkansas to show up and send these seniors out the right way. And what we want is to improve and perform better than we did this past week."
There is still a chance for a three-way tie in the SEC West. Is that part of your focus?
"I think what you do is you really focus on practicing well this week," Petrino said, "doing a good job in our preparation, making sure that our seniors understand this is our last time we get to play in this stadium, making sure all the younger players understand that we're going to send this group of seniors out with a win in their last game in this stadium, and that's how you have opportunities open up for you.
"You keep a narrow focus on what you need to do on a daily basis."
Concerning the seniors, Petrino said the group has accomplished a lot. He remembers the way that group came in as a freshman, the knocks they took and the way they competed with eagerness.
"We all came in together and there were some hard times," Petrino said. "Things weren't going well and they stayed eager every day in practice. They built things and eventually got to a BCS game. This group has done a lot."
Defensive end Jake Bequette said the team "was not real happy" with the drop in BCS.
"But what we have to do is play hard on Saturday," he said. "If we take care of our business, the BCS business will take care of itself.
"The BCS is a whole different category. As players we have to take care of our area. We have some great opportunities to showcase our abilities on national television and that will help us in the BCS."
Senior wideout Jarius Wright said he remembers those tough days four years ago.
"We took our beatings," he said. "I've heard Coach Petrino and Jake talk about those years and it was tough. But we've accomplished a lot.
"The last game in the stadium, the last time to run through that A on Saturday night is going to be very emotional."
Petrino said he was encouraged about the chances of defensive end Tenarius Wright returning this week.
"It's possible," Petrino said. "There is the possibility. We go into the week encouraged."
Petrino was asked if Marquel Wade would be back on the field this week after serving a one-game suspension.
"He has the opportunity," Petrino said. "We'll see how the week goes."
Petrino was asked on the role of Colton Miles-Nash, who was moved back to defensive end after starting the season at tight end.
"You know, in the Ole Miss game I'm seeing him standing on the sideline and we're not playing him a whole lot, and that's a big man that played well a year ago at defense end, so after the game I just made a decision that I'm going to get him back on the field, get him more reps and move him back over at defensive end," Petrino said. "And he came out and I think he had 17 snaps. We didn't have many snaps on defense, that's a good thing, but he played 17 and did a nice job, a real nice job.
"Our defensive line played well. They played fast and physical. We got after them all week long about ‘We're getting better, we're improving, now it's time to put it all together'. Our inside guys were playing hard fighting for reps. They're all fighting to get more reps, that's what they want to do. And then, we've got some bodies back on the edge and Jake (Bequette) is back to full speed. His injury was a bad injury. He just hung in there and kept getting better. He wasn't the same player his first couple games back, but certainly we saw Jake Bequette the other night."
