Georgia will be a little thin at running back when spring practice opens this Saturday. Freshman Keith Marshall suffered a pulled hamstring while running track. He's expected to miss at least half of spring practice. That leaves Toddy Gurley, Brandon Harton, and a few walk-ons left to carry the ball. Georgia also announced that fullback Alexander Ogletree will not be back with the team due to medical reasons. Ogletree is the twin brother of linebacker Alec Ogletree.
