With usual starter Ben Grubbs hobbled by a toe injury, Mark LeVoir is poised to make his second consecutive start at left guard when the Ravens visit the St. Louis Rams Sunday.

It’s development that has required a certain degree of flexibility from LeVoir, who has been an offensive tackle through most of his five-year career in the NFL.

“Obviously, things are lot closer, a lot quicker and more on top of you,” LeVoir said of lining up at guard instead of tackle. “You’re not in space. Obviously, your vision’s a little bit different because you’re usually down in a three-point stance. So the footwork and landmarks are all a little bit tighter.”

LeVoir – not Andre Gurode, a five-time Pro Bowl center who is listed as the top backup at both guard positions – got the nod in Sunday’s 26-13 loss to the Tennessee Titans, and although LeVoir did not stand out for any glaring mistakes, he was critical of his performance.

“I played all right, but I definitely think I could have done things a lot better,” he said. “Need to improve and keep working to get better.”

LeVoir said he wasn’t sure whether he or Gurode would start at left guard if Grubbs – who did not practice Wednesday – continues to be troubled by his injured toe.

“It’s a new position, but when your number’s called upon, you’ve got to play it,” LeVoir said. “Wherever the coaches put me, I’ll be there.”
