Moreno spent nearly the entire preseason in a green no-contact jersey while battling shoulder soreness, and the injury caused him to miss reps at returner last week.
"Knowshon had a spell where he couldn't get any reps, and I guess he kind of fell by the wayside," Richt said.
The words came with a bit of a sly grin from Richt, however, and when he said he may not know until game day who would return punts, the possibility of revisiting the plan in a later game was quickly resurrected.
"I just think that if you get the ball to Knowshon in the open field on a punt return with the kind of blocking we've been getting over the years, that's a pretty valuable place to be," Richt said.
"He just didn't some of the work here toward the end. It's still a pretty tight competition, but I wouldn't count Knowshon out of returning some punts before this year is over. He's very capable, and he'd be excited about the opportunity."
