Attempting to slow down the Razorbacks this weekend will be the Tennessee Volunteers.
Kickoff in Fayetteville, Ark., is on Saturday at 6:04 ET (TV: ESPN2).
"We are understanding the scheme more," Tennessee defensive end Jacques Smith said. "We're feeling a little more comfortable with it, and the coaches know which calls players prefer more. (Our progression) is going really well."
The atmosphere at Donald W. Reynolds Razorback Stadium and mood around the team is likely to be pretty electric as 17 seniors will be playing their final game on campus.
No. 8 Arkansas (8-1, 4-1 Southeastern Conference) enters with plenty of momentum as winners of 20 of their last 25 games. Since 2008, the Volunteers are 22-25.
It will be the fourth opponent in five weeks that Tennessee (4-5, 0-5) has faced undefeated or with just one loss.
Quarterback Tyler Wilson has already passed for 2,626 yards and 15 touchdowns. His passer rating is 144.65. Lining up outside as weapons are three of the school's all-time best as Jarius Wright (second-2,629 yards), Joe Adams (fourth-2,274) and Greg Childs (seventh-1,946) rank in the top 10 in career receiving yards.
In the 44-28 win over South Carolina last week, against the previously-ranked No. 1 pass defense in the country, Wilson completed 20 of 37 passes for 299 yards with two touchdowns and an interception. Wright caught four balls for 103 yards and both scores.
Slowing down Petrino's passing attack will be vital to Tennessee's efforts if it wants to pull off the upset.
