OU coach Bob Stoops refused to disclose the severity of the injury, nor how long he expected Simmons to be out.
But the injury to the two-year starter is a blow to an offensive line still trying to develop consistency.
With Simmons out, the Sooners will use some combination of junior-college transfer Tavaris Jeffries, true freshman Tyler Evans and sophomore Stephen Good at the two guard spots.
Jeffries has started the last two games at right guard. Evans started there the two games before that. Good, the projected starter before the season at right guard, has been Simmons’ primary backup on the left side.
