LSU quarterback Brandon Harris (6) drops back to pass behind the protection of offensive tackle Toby Weathersby (66) and offensive lineman Josh Boutte (76) in the second half, Sat., Sept. 3, 2016 at Lambeau Field in Green Bay, Wisconsin. LSU took the lead briefly at 14-13 after trailing 13-0, but were defeated by a Wisconsin field goal in the waning minutes.

LSU's other tackle missed practice Tuesday.

Right tackle Toby Weathersby was not present during the limited portion of practice open to reporters, joining left tackle KJ Malone as key absentees from drills. Malone has missed the last month of practice after suffering a left knee injury at Florida. 

Weathersby's absence is unclear, but he's battled a host of injuries. The junior and second-year starter underwent several off-season procedures this year, OL coach Jeff Grimes said this spring. He missed the Tigers' loss to Troy and win over Auburn and portions of the game against Florida — the latter, Weathersby said, with "heat-related headaches."

Weathersby wore extra protection on his helmet during the game at Florida, meant to lessen impacts to the head. 

Sophomore Adrian Magee replaced him in the starting group during practice Tuesday. Magee and true freshman Austin Deculus are behind Weathersby at right tackle. Saahdiq Charles, a rookie as well, has replaced Malone at left tackle.

The Tigers (6-3, 3-2 Southeastern) host Arkansas (4-5, 1-4) at 11 a.m. Saturday in Tiger Stadium.
