Rambo, Georgia's second leading tackler last season, sat out the Bulldogs' 35-21 loss to Boise State Saturday.
"I broke a team rule," he said. "It was a selfish mistake. I will not allow it to happen anymore. It was a big mistake that I did. … It messed up the team goal by me sitting out that one game. I'm not saying we could have won, but I know I could have helped the team out as much as I can and the results of the game could have been different."
Rambo declined to say what he did to warrant the suspension or when he knew he wouldn't play.
"I'd rather y'all talk to coach (Mark) Richt," Rambo said.
With Rambo watching, Boise State's Kellen Moore completed 28 of 34 passes for 261 yards with three touchdowns.
"It was very tough and frustrating," Rambo said. "It really stressed me."
Rambo returns Saturday against No. 12 South Carolina.
"I'm hungry," Rambo said. "That's all I can say — I'm hungry."
Rambo said he worked with the first team in Tuesday's full pads practice and Sanders Commings, who started at safety in the opener, worked at cornerback.
"Sanders is now available, he'll be more freed up to play corner," Richt said. "Right now he can play both. It's just good to have that kind of versatility."
Said Rambo: "There's no telling where he might end up at."
Crowd noise hurt communication
Part of Georgia's problems in pass protection Saturday were communication issues.
Georgia gave up six sacked sacks — including a couple of times when its tackles didn't get off on the snap well — and had several false start penalties.
"There were a lot of times we couldn't hear the snap count," said guard Chris Burnette, who took every snap on offense in his first college game. "We don't like to make excuses, but there were a lot of times we weren't in the right position to do what we do. The crowd was surprisingly loud. We weren't really expecting it to be that loud. There were a couple of times when people were late off the snap."
Boise State's fans were vastly outnumbered by Georgia fans in the Georgia Dome, but the Bulldogs still had trouble as they tried to operate the no-huddle offense near where the Broncos' supporters were sitting.
Richt discovered that going to a silent cadence would help the Bulldogs' offense.
"We did start out the game with the cadence and then we had to change to a non-verbal cadence," Richt said. "Then we weren't jumping offsides but we were late off of the ball. That was part of our issue with the protection."
Fending off Boykin, Smith
After that, it's anyone's guess.
"Not to say that a third back won't get an opportunity, but those guys are not only competing for the No. 3 tailback job, but they are kind of competing against how many reps Boykin and Smith can take in a ballgame," Richt said.
Smith wasn't used on offense against Boise State as he returned from a foot injury.
This and that
Dallas Lee is set to start at guard with Chris Burnette. Kenarious Gates (ankle) did not practice Tuesday and likely wouldn't start if healthy. "If you base it solely on the game, (Lee) would be your starter this week," Richt said. ... Nose guard Kwame Geathers (shoulder) did not practice Tuesday. Defensive coordinator Todd Grantham said he will need to wait for today's medical report to know his status. ... Outside linebacker Cornelius Washington (two quarterback pressures and a tackle Saturday) "probably had his best game since I've been here, just in being consistent in doing everything we asked him to do," Grantham said. ... Receiver Marlon Brown (undisclosed) practiced in a noncontact jersey … Offensive coordinator Mike Bobo called Tuesday "a competition day" for players fighting for jobs. Freshman receiver Malcolm Mitchell had "a great day," Bobo said. ... Inside linebackers coach Kirk Olivadotti hinted at more than just Mike Gilliard, Amarlo Herrera and Jeremy Sulek playing at injured Alec Ogletree's inside linebacker spot. "There's going to be even more guys, guys you haven't even thought of yet," Olivadotti said. Asked who? "Maybe me," he said.
