Terrace Marshall Jr. catches a pass while playing for Parkway in 2016.

Terrace Marshall is not full speed just yet, but that doesn’t mean he’s not impressing head coach Ed Orgeron.

Marshall, the prized 2018 signee out of Shreveport who enrolled in January, is still recovering from a serious ankle injury he suffered last September, but he’ll participate when LSU begins spring practice Sunday, Orgeron said in an interview with The Advocate on Thursday.

“He’s coming. He’s smooth,” Orgeron said. “He’s going to be fine. He’s just not full speed yet. He’s going to be fine, going to practice.”

Orgeron estimates that Marshall is about “80” percent. He dislocated his ankle and fractured a leg bone six quarters into his senior season at Parkway last fall.

He’s far from the only Tiger recovering from injury.

Offensive tackles Austin Deculus (wrist) and Saahdiq Charles (shoulder), both sophomores, underwent procedures this offseason. They are out for spring, Orgeron said.

Fifth-year senior safety Ed Paris (knee) and freshman defensive end Davin Cotton (knee) will not begin spring practice with the team. They could join drills later as they recover from injury. Cotton, a mid-year enrollee out of Evangel, ruptured his ACL in the season opener of his senior season last fall. Paris suffered the same injury in September of last year, ending his would-be senior season.

“Ed’s coming along. He’s not ready to go yet,” Orgeron said. “I don’t know how far out he’s going to be, but he won’t start at the beginning (of spring).”

Ducre moves, for now, to running back

David Ducre is on the move – again.

Ducre, a one-time fullback who moved to LSU’s H-back-type position last season, is a tailback – for now, Orgeron said.

“David wanted the chance to play tailback, so we’re giving him a chance to play tailback,” the coach said.

Ducre joins a position group that is slow on returning production. Orgeron says senior Nick Brossette will receive the first snaps in spring ahead of sophomore Clyde Edwards-Helaire and freshman Tae Provens.

Ducre, a 6-foot, 235-pound Slidell native, signed with the Tigers in 2015 as the nation’s top-ranked fullback. He’s been used intermittently since, getting his most playing time in the F-back position under then-coordinator Matt Canada. The F-back was a blend of tight end and fullback, more of an H-back.

The H-back position still exists in LSU’s new offense under Steve Ensminger, Orgeron said, but with some tweaks. The tight ends, previously coached by Ensminger, will now be coached by offensive line graduate assistant John Decoster. Decoster and the tight ends will work alongside offensive line coach James Cregg when practicing the run game, Orgeron said. In the pass game, Decoster and the tight ends will work with pass game coordinator Jerry Sullivan and receivers coach Mickey Joseph.

“There will be sometimes where that extra tight end will be used as a moving tight end, like an H-back. There will be another time where that tight end will be used in the fullback position,” Orgeron said. “Tommie Robinson last year only coached the tailbacks. He’ll coach the tailbacks and the fullbacks. They’re in his room. When that position has to be a (H-back), they’ll go in with John Decoster. We’re kind of specializing in everybody’s skills.”
