LSU starting guard Will Clapp donned a walking boot on his right foot during the team’s walk-through at Lambeau Field on Friday afternoon.

A source says the injury is “not serious" and that he's wearing the boot for precautionary reasons. Fellow tackle K.J. Malone posted a photo of Clapp in the boot. 

His playing status is unclear for the Tigers’ season opener on Saturday against Wisconsin. Clapp, a redshirt sophomore, served as one of LSU’s premier run blockers last season, pulling often from his right guard spot to pave the way for running back Leonard Fournette.

Clapp was listed as LSU’s starting left guard in the program’s depth chart released Monday. Redshirt sophomore Garrett Brumfield is listed as Clapp’s backup. Maea Teuhema, the left guard last season, could also play the position.

Teuhema is fully recovered from an ankle injury that, one, forced him to miss the first week of preseason camp and, two, lost him a projected starting spot at left tackle. K.J. Malone, Karl Malone’s son, and sophomore Toby Weathersby are expected to man the left and right tackle positions, respectively.

Clapp, a New Orleans native, started all 12 games last season and landed on at least two All-Freshman All-American teams and was on the SEC All-Freshman coaches’ team.
