Brown, who hasn't played since the Oct. 6 Tennessee game due to a broken collarbone, practiced with contact and pronounced himself ready to go, almost.
"It felt fine, no problem," Brown said. "It's still day-to-day, but I think I'm ready to go."
Brown averaged 68.8 yards per game and 5.4 yards per carry before his injury, but Moreno has averaged 180.3 yards per game in Brown's absence.
Richt has steered all week clear of questions regarding how Brown's return his rotation with Moreno, but running backs coach Tony Ball has a definite opinion.
"I don't factor in (previous performance)," Ball said. "Right now the team has a flow. Knowshon has done well. You don't demote someone because of (another player's) seniority. We're in the business of winning games. That's what we do, and we feel that both those young men can help us win games."
Offensive lineman Chris Davis said Brown looked impressive in Wednesday's practice.
"It's nice to have those fresh legs back," Davis said. "It's exciting to have a talented guy like Thomas back, and I'm just excited for Saturday to see what he does."
Thomas Brown also dodged the question of a rotation.
"I feel bad for whoever has to make that decision," he said.
