But Petrino said Arkansas also intends to spend more time with backup Tyler Wilson after the true freshman made his collegiate debut in the fourth quarter of the 49-14 loss.
Petrino said Wilson — who played over redshirt freshman Nathan Dick — will get more second-team work this week.
"He'll take more reps with the two's and get more work," Petrino said. "We've got to work at bringing him along.
"He's a young man that has very good instincts, very good instincts in the pocket, very good vision, can be accurate throwing the ball. We need to bring him along."
Wilson went 4-for-7 for 27 yards with one touchdown and one interception last week. The touchdown pass, which was caught by Michael Smith, came on his first series.
Arkansas players said Wilson wasn't perfect, but they were impressed with his play when the game was out of reach.
"He seemed pretty calm in the huddle," Smith said. "I liked his approach. ... That was a good thing to just get some experience under his belt."
Arkansas couldn't play any of its backup quarterbacks against Western Illinois and Louisiana-Monroe because of the close games. Casey Dick had logged every snap until he was pulled with 12:47 left in Saturday's game.
Petrino had named Nathan Dick his second-team quarterback heading into the opener, but said Wilson was his choice to play because of his work on the practice field.
"In practice he had performed better this past week and he's a little bit more explosive in Shotgun," Petrino said. "So it's just a decision that we came down to make."
Reserve receiver Marques Wade tore a ligament in his knee on a special teams play in the first half and will be out the rest of the season. Wade, who will undergo surgery sometime this week, was making his season debut after being suspended for the first two games.
In addition, starting receiver Lucas Miller sustained a concussion and is questionable for Saturday's game. The junior has six catches for 105 yards in three games.
"It's just how he comes back from it," Petrino said of Miller. "We'll evaluate his status (today)."
Texas will be without Blaine Irby after the tight end suffered a knee injury against Rice. Irby was third on the team with 10 catches for 95 yards and two touchdowns.
No Overhaul Coming
Don't look for Arkansas to rip up its defensive playbook despite its struggles. Petrino said a complete overhaul of the scheme is not in the works.
"You can't re-evaluate scheme," Petrino said. "The one thing that you do when you struggle is you don't try to change and keep changing things because then you never improve. So what we need to do is improve on what we're doing and do it better. Do it more precise."
Arkansas is one of the nation's worst defenses, statistically speaking, after three games.
The Razorbacks are 101st out of 119 teams in scoring defense (33.3 points). They are 94th against the run (185.3 yards) and 55th in total defense (335 yards).
Texas junior Colt McCoy's transformation from struggling quarterback to prolific passer continued last week.
McCoy threw for 329 yards and four touchdowns in the 52-10 win against Rice. McCoy, who has thrown for 833 yards and 11 touchdowns in three games, also broke the school's record for career touchdown passes (62).
McCoy enters the Arkansas game ranked third in the nation in pass efficiency with a 206.5 rating.
"He's a more confident person," Brown said of McCoy, who had his share of struggles replacing former Longhorn Vince Young in 2006 and 2007. "It's a guy who is in charge and knows that he has made his place at Texas now."
• Details for the Arkansas-Florida game on Oct. 4 were set Monday. The game will be televised by Raycom Sports and will kick off at 11:30 a.m.
• It seems that freshman quarterback Jim Youngblood will try to play baseball at Arkansas next spring. The former Camden Fairview standout, who has been working with the scout team this fall, is listed on the baseball team's roster.
