Smith suffered a hyperextended neck during last week's 18-13 win over Tennessee. The junior leads Georgia with 110 carries for 512 yards rushing and three touchdowns.
Even if Smith is able to play, Coach Mark Richt says he wants to do a better of job of getting more carries for Milton and true freshman Tyson Browning. Next in line at tailback is Ronnie Powell, who also could be in the playing rotation if Smith is held out with the injury.
Through six games, Milton is second on the team with only 20 carries for 97 yards. That total includes his biggest carry of the year, a 25-yarder on a fourth-and-two play that allowed Georgia to run out the clock against Tennessee.
Milton is a more accomplished blocker than Browning, who has nine carries for 56 yards.
Milton said he is looking forward to getting more snaps in practice and in Saturday's 12:30 p.m. game for No. 5 Georgia "to just get experience.''
Said Milton: "Like on the (25-yard run), I should have scored. I think had I been carrying the ball in practice more I would have gone on and finished it off. ... It's like going to work. You learn with experience.''
"We have no problem with Milton going in the game at any time,'' Bobo said. "We wouldn't change the game plan at all (if Milton started).''
Smith was not available for comment Monday.
