Redshirt freshman Darrell Williams will earn his first start Saturday at Army in place of injured Ed Hazelett, who left the Georgia State game with an ankle injury.

Hazelett has started every game at right tackle for WKU, but Petrino said Williams “played well” when finishing the game in Hazelett’s place.

“He’ been, basically, the last month trading off every four plays in practice, so he knows what he’s doing,” Petrino said. “If he doesn’t, Cam (Clemmons) will tell him. He gets the bonus of playing next to Cam Clemmons because Cam knows the offense really well.”

Clemmons has started at right guard the past six games. With the addition of Williams, that makes it three redshirt freshmen starting on the offensive line for the Toppers.

However, Petrino isn’t worried about the youth on the line.

“I’m excited about it,” Petrino said. “I think they’ve played well and as many reps as they get in practice, I still think the offensive front is one of our strengths.”
