LSU’s most productive freshman defensive tackle has entered the transfer portal, On3’s Hayes Fawcett reported on Thursday afternoon. Earlier this week, LSU announced that Mathis was locked into staying for 2026, but four days later he plans to enter the portal.

Mathis played in 12 games last year, ending with nine tackles and was a rotation piece in the defensive tackle room in year one. At 6-foot-2 and 285 pounds, Mathis impressed with his potential to shoot gaps and take on blocks at his size. He’s originally from Savannah, Georgia and now is set to look for his next school.

LSU has added Clemson defensive tackle Stephiylan Green and Auburn’s Malik Blocton to its defensive line unit already to pair with junior Dominick McKinley. A talented group of freshmen are also coming in, including Richard Anderson and Lamar Brown, the No. 1 player in the country.

Mathis joins Zion Williams and Ahmad Breaux as other defensive tackles to enter the portal.
