Petrino said Monday the team has shown plenty of enthusiasm and remain focused, so he feels good about effort to get ready for the game.
Arkansas (3-1) had this past weekend off. The Razorbacks are ranked No. 11 in the AP Top 25 poll.
The Aggies (3-1) are coming off a 38-35 last-second loss to Oklahoma State on Thursday.
Petrino says Texas A&M poses a dual threat because they can thrown and run the ball effectively. He said the Razorbacks will have to do a good job preparing for the Aggies defense, which runs a lot of blitzes.
