Bry’Kiethon Mouton has been waiting for his moment.

LSU’s sophomore fullback scored on a 5-yard run early in the third quarter of Saturday’s spring game in Tiger Stadium, the only score of the day for the White team in a 17-7 victory by the Purple squad. The touchdown was with the Tigers’ No. 1 offense operating against the No. 2 defense.

“They wanted to see if I could handle the ball. Coming out of high school I was a tight end,” said Mouton, a former standout at Acadiana High in Lafayette. “They wanted to see if I could make a play and I did.”

The fullback dive has long been a staple of LSU’s offense. But Mouton had to do more than just smash into the line, making a “football move” as a hole opened off right tackle as he powered across the goal line.

“It was off of a lot of repetition,” Mouton said. “The linemen were across my face so I cut it back fast. It was something that came to me naturally.

“Coming into the season nobody really looks for our fullbacks to get the ball and make plays. It’s going to be a good look for me and the offense.”

Mouton expects to be locked up in a battle for playing time come practice in August with junior John David Moore, who sat out this spring recovering from a knee injury.

“It’ll be good competition,” Mouton said. “He’s a good player and I’m a good player. We’re going to see where it goes from there.”

Clapp to undergo surgery

Will Clapp, a projected starter at guard next season, is scheduled to have surgery for a sports hernia next week, he said.

Clapp did not participate in LSU’s spring game — one of three projected offensive linemen to miss the game. Rising sophomore Toby Weathersby, who Les Miles anointed a started at right tackle earlier this spring, also missed the game with an unspecified injury. Ethan Pocic has missed all of spring while recovering from hip surgery.

K.J. Malone said last week that Weathersby was “nicked.” Malone replaced him in the starting lineup at right tackle Saturday, as he did during the last week of spring practice.

Source: Upchurch to transfer

Fullback-turned-receiver Tony Upchurch plans to transfer, a source told The Advocate on Saturday.

A redshirt sophomore, Upchurch played in the final eight games of last season at fullback. He was moved to receiver during the offseason.

Upchurch was absent from, at least, the last two weeks of spring practice and did not participate in the spring game.

Washington, Alexander out

Tight end Jacory Washington and linebacker Donnie Alexander joined Clapp and Weathersby among those who were expected to participate in the spring game but did not.

Washington’s injury was not known. He watched from the sideline without pads. Alexander suffered a concussion earlier in practice this week, Miles said.
