Moss is the son of Pro Football Hall of Fame receiver Randy Moss. He played one season for the Tigers after transferring from NC State.
The redshirt junior has just 17 games of collegiate experience but played a significant role in LSU's national championship run. He caught 47 passes for 570 yards and four touchdowns in 2019, making a number of highlight-reel receptions.
He caught four passes for 99 yards and scored a touchdown against Oklahoma in the College Football Playoff semifinals, then scored twice versus Clemson in last week's title game.
The 6-foot-3, 249-pounder is likely to be targeted on Day 2 (rounds 2-3) or early Day 3 (rounds 4-7) in April's draft and a successful combine would give him the chance to be one of the first tight ends selected.
Moss is the ninth Tigers player to opt against returning to school.
