True freshman Emery Jones made his first career start Saturday against Mississippi State.
With right guard Anthony Bradford out for the Southeastern Conference opener in Tiger Stadium, LSU used a different offensive line for the third straight game as it tries to settle the group.
Redshirt sophomore Miles Frazier moved inside from right tackle with Bradford out. Frazier has now played left guard, right guard and right tackle through three games.
Jones, a freshman from Baton Rouge, has impressed the staff since he arrived this summer. With him in the lineup, LSU started true freshmen at both tackle spots.
The rest of the first-team line had freshman Will Campbell at left tackle, sophomore Garrett Dellinger at left guard and redshirt junior Charles Turner at center. Dellinger opened the season at center before LSU inserted Turner in the lineup last week.
Backup offensive tackle Marcus Dumervil was also unavailable against Mississippi State, and though he dressed, senior Cameron Wire did not warm up on the first- or second-team offensive line.
