ATHENS — Georgia football sophomore noseguard Jordan Davis is doing what he can to keep his weight under control and anchor a thin defensive line.

Coach Kirby Smart said following Tuesday’s practice he’s pleased with Davis’ effort but concerned about his defensive front at this stage of spring drills.

“Jordan is pushing hard, Jordan works really hard, he’s working to control his weight,” Smart said after the fourth of 15 spring practices. “Jordan’s not playing to the level that he was mid-season, end of the season. He’s not there right now, but he’s working hard.

“Jordan comes in and works cardio more than anybody we’ve got. If I ran as much as Jordan my wife would be happy because I’d be skinny. But Jordan’s got to fight that battle and he knows it.”

The 6-foot-6, 330-pound Davis, a 2018 FWAA Freshman All-American, missed the Bulldogs’ 28-21 loss to Texas in the Sugar Bowl on account of a back injury.

The Bulldogs are missing veteran defensive linemen Julian Rochester (knee surgery) and Michail Carter (shoulder surgery) this spring.

David Marshall remains limited on account of the foot surgery that sidelined him last season.

Smart was asked how other players on the defensive line were emerging.

“What other guys? We ain’t got anymore, we don’t have any,” Smart said. “Defensive line is, like, super thin. I guess I’m whining to the masses because everybody will tell you ‘we don’t have enough defensive linemen.’ You know?

“We don’t have enough depth there. I thought Devonte Wyatt was a guy that’s been really competitive and done some good things. He was starting to grow up in the season.”

Smart is optimistic about the future of the defensive front.

“But there’s something about these guys in their second spring where they start to click and get it,” Smart said. “We need it. Our health is on the way there. It’s just not here.”

Injury update: Georgia freshmen early enrollee linebackers Rian Davis and Trezman Marshall were both seen going through non-contact drills on Tuesday.

Davis underwent surgery on his knee in October after suffering the season-ending injury on Sept. 29.

Marshall had shoulder surgery following his senior season in December.
