Georgia could have to do it with three of its best players on the defense, the two in the front seven either limited or out for the game.
The Bulldogs were already without Thorpe-Award winner and All-American cornerback Deandre Baker, who announced he’s skipping the game to prep for the NFL Draft.
Walker, meanwhile, was back in pads on Saturday and going through thud contact drills for the first time since aggravating a groin injury in the SEC Championship Game.
Freshman All-American candidate Jordan Davis was also back working with the defensive tackles on Saturday after going through warmups off to the side in Friday’s practice.
But Smart said Davis also will be a game-time decision and might also be limited to situational playing time.
“Both of those guys have struggled to get back 100 percent.”
The Bulldogs’ offensive line featured Trey Hill working at right guard, while Cade Mays comeback from a shoulder injury put him working behind Andrew Thomas at left tackle.
Redshirt sophomore Ben Cleveland, who is not yet 100 percent after suffering a broken fibula on Sept. 22, has been working as the backup right tackle.
