Coach Mark Richt made the announcement Thursday.
The Bulldogs lost their top two rushers from 2009 when Washaun Ealey transferred and Caleb King was ruled academically ineligible.
Incoming freshman Isaiah Crowell, a high-profile signee, is listed on the depth chart at tailback along with Carlton Thomas, Samuel and two others players.
Samuel played tailback as a freshman and sophomore, but moved to linebacker last year before injuries caused him to spend 2010 as a redshirt.
In 22 games, including six starts, Samuel has 528 yards rushing and three touchdowns in 114 career carries.
