"I tore my hamstring in the Duke game," McCarthy said. "I was going down on kickoff and cut the wrong way and just tore my hamstring. Midway through the game, we scored and I ran down and it popped. My right hamstring. I was on the field, I saw it all, including the interception to win us the game."
McCarthy talked about what the defense needs to do this week.
"We have to guard against the pass," he said. "They have good receivers. The quarterback can scramble. If we hold them like we did Texas A&M, we'll be fine."
McCarthy and the rest of the team understands that this game is just as important as any other on the schedule. He talked about that.
"We have to take it game by game, Duke is just another step in our season," he said. "Hopefully we come out the winner."
Duke is the first game on the ACC schedule so that adds extra importance to getting the win tomorrow.
"It is real big in the ACC," he said. "This can be used as a confidence game and hopefully we can come out with a win."
While the defense has been playing well, the offense showed signs of life against Texas A&M last week.
"As far as coming into Duke, our offense has a lot of momentum as far as defense covering the pass, reading our run keys," he said. "It was real effective on film and we hope to bring it into Duke."
McCarthy is hoping this year's game doesn't come down to the final seconds like it did las year. He recalled last year's final seconds.
"Coop made a good play on the ball at the end of the game and saved us it was real big for us," he said.
