The two defensive stars were suspended for the first four games of the season after failing drug tests during spring practice, although Mark Richt's coaching staff never revealed beforehand the length of either player's suspension.
Richt played coy up until the last minute, saying this week that the players will be back on the team if they are dressed during pregame warmups. Both players were carrying their pads as they entered Sanford Stadium alongside their teammates during the "Dawg Walk" just after 2 p.m.
Both players rank among Georgia's most valuable defensive performers.
Rambo was a first-team All-American last season after leading the SEC and ranking second nationally with eight interceptions.
Ogletree missed half of the 2011 season with a broken foot, but still finished seventh on the team with 52 tackles. He led the team in tackles in each of Georgia's final five games last season and is ranked as the No. 19 player in ESPN Scouts Inc.'s 2013 NFL draft prospect rankings.
