Just a month ago, the long-awaited Jackson Arnold era was underway at Oklahoma. The highly touted quarterback seemed ready to take his place among the greats at a school that has produced four Heisman winners this century at the position.

What was a big-time matchup between a pair of top-15 teams fizzled in the first half when Oklahoma’s offense couldn’t muster more than three points. Turnovers and inconsistent play from Jackson Arnold led to a 19-3 deficit at halftime. Arnold was benched just before halftime in favor of true freshman quarterback Michael Hawkins.

Tennessee football demolished Oklahoma with its powerful defensive line, getting a win against the Sooners to open SEC play.

The Sun Devils are 3-0 on the season, ahead of its Big 12 opener against Texas Tech, and national analysts are starting to take notice.

However, rarely has the practice been targeted directly as it was during Tennessee and Oklahoma's game Saturday. In the game's first quarter, Sooners defensive lineman Da'Jon Terry appeared to go down with an injury.
