A fourth player is not returning to the LSU football program.

Sci Martin, an edge rusher from New Orleans, has transferred to East Mississippi Community College, EMCC coach Buddy Stephens confirmed Friday afternoon.

Martin, a 6-4, 255-pounder, did not play this season and sporadically attended practice. He suffered a serious knee injury during spring practice and never seemed to fully recover. He recorded two tackles and played in five games as a true freshman in 2016. 

Martin signed with LSU in 2016 out of McDonogh 35 as a top-25 defensive end prospect in the class. He played the hybrid outside linebacker/defensive end role in Dave Aranda's 3-4 defense, the same one Arden Key manned. 

Martin is the fourth player to depart from the team, joining fullback Bry'Kiethon Mouton, tight end Caleb Roddy and defensive back Xavier Lewis. 

LSU's depth on the defensive line and at the outside linebacker positions is strong and will get deeper in the fall. The Tigers signed five defensive tackles and two hybrid-type edge rushing players in the 2018 class, including mid-year player Travez Moore and Jarell Cherry.

Cherry and Moore join sophomore K'Lavon Chaisson and redshirt sophomore Ray Thornton at Key's old position. The Tigers also return Andre Anthony, a highly touted signee in 2016 who redshirted as a freshman and missed 2017 after a season-ending injury in camp. Martin would have likely been somewhat buried on the depth chart.

Martin joins one of the nation's junior college powerhouses. Located in tiny Scooba, Mississippi, East Mississippi won a fourth junior college national title last season since 2011. Lindsey Scott, the former LSU quarterback from Zachary, led the Lions to the 2017 championship. 

EMCC was the featured program on Netflix's first two seasons of "Last Chance U."
