Senior Shawn Williams sustained a knee injury in the morning scrimmage at the Woodruff practice fields. Georgia already was missing Bacarri Rambo with what coach Mark Richt said is a hamstring injury.
Richt said Williams' injury won't require surgery, but he did not know if he will be able to practice during the final week of spring practice.
"He's in there (in the training room) doing fine right now," Richt said of Williams, who grabbed an interception in both scrimmages so far.
The 6-foot-2, 207-pound Moore, from Griffin, appears headed for a frontline role since Rambo is facing a four-game suspension after his second violation of Georgia's drug testing policy.
Of Moore, Richt said: "He's coming. He's a very aggressive football player when it comes to coming up to make a tackle. He's a good athlete. He's learning a lot. He's getting a lot better. He's going to have to play for us. He's going have to be able to function for us."
Marshall, Samuel doubtful for G-Day
Freshman tailback Keith Marshall is unlikely to make his Sanford Stadium debut Saturday in front of fans on G-Day.
Richt called Marshall "doubtful" to play due to a pulled hamstring. He did not scrimmage and hasn't practiced for a week.
Fullback Richard Samuel's status for G-Day is uncertain due to a concussion.
"I would say the chance of Keith going is probably not very good," Richt said. "It's hard to say on Richard."
Richt said he hoped to have teams divided up for the G-Day game by the end of the day Monday, but it won't be released until later.
Asked if players will draft teams like last year, Richt said: "That's still up for debate. … I kind of wanted to see how we came out of this scrimmage just to see where we're at."
Nose guards too much for O-line
Georgia's offensive line continues to be having a tough time this spring.
"You've got two of the biggest nose guards around and maybe two of the better ones around, too," Richt said. "They're making it tough on our centers. Even when our centers do everything right, they're still just big strong guys that know what they're doing and are just penetrating into the backfield quite often."
"It's been kind of a round-robin," Richt said. "We haven't settled on anybody yet."
Geathers was credited with two sacks on Saturday.
"The offensive line is still being challenged every day," Richt said. "There still wasn't a lot of room to move the football. When the ball did get moved it was moved moreso through the air. The o-line's definitely got a way to go. There's no doubt about that."
QBs get going
Georgia's quarterbacks threw four touchdown passes in the scrimmage.
Aaron Murray completed 8 of 13 for 125 yards and a touchdown. Hutson Mason went 12 of 19 for 151 with two touchdowns and two interceptions. Walk-on Parker Welch was 5 of 10 for 57 yards and a touchdown and Christian LeMay completed 3 of 6 for 28 yards and an interception.
"We threw and caught it a lot better," Richt said. "It started out not very good, but as the scrimmage went on more plays were made."
Quarterbacks are sacked by touch during the scrimmage.
"You're trying to make a judgment on whether a play would have been a sack or not," Richt said. "We tried to err on the side of letting the ball get thrown."
Richt said the defense still was "pretty stout."
This and that
Georgia already has double-digit commitments for its 2013 class after getting four verbal pledges Thursday and Friday. "Sometimes it hits faster than others," Richt said. "You just don't know. We've done a good job of getting offers out there and pursuing these guys and letting them know we want them and getting them on the campus. It's been going good." …Georgia has three more practices this week before Saturday's 3 p.m. G-Day game.… Walk-on safety Connor Norman returned an interception for touchdown. …Cornerback Devin Bowman "got the wind knocked out of him," but returned.
