The absence left the Bulldogs short on depth, with walk-on senior Jeremy Sulek receiving most of the snaps to fill in.
Freshman Amarlo Herrera also saw time at the position.
Sophomore offensive tackle Kenarious Gates was carted off the field in the second quarter after falling awkwardly and injuring his knee at the end of a run play.
That led to rumors about Rambo's status for the season opener against the Broncos. Some wondered if he had been suspended.
"At the appropriate time, if anybody has anything like that, I'll let you know," coach Mark Richt said earlier in the week. A university official said there was no word on why Rambo was held out. Williams and Commings got the start, with walk-on Conner Norman also playing at the position in the first half.
Crowell forced to wait for first carry
Highly touted freshman Isaiah Crowell said earlier this week he'd started every game of his career—at every level of play.
After a month of anticipation, junior running back Richard Samuel snapped Crowell's personal streak. Samuel started the game for the Bulldogs, carrying the ball six times for nine yards in the first half.
Crowell was inserted on the second drive; the first carry of his career went for a two yard loss.
He finished the first half with 10 rushes for 36 yards.
Change of scenery
A 45-19 loss to the Volunteers spurred Bobo to move to the sideline closer to his players and "just look in their eyes and call the play and try to get some belief and some confidence," he said at the time.
The move did not lead to ideal results—the Bulldogs managed only four first downs in the first half.
This and that…
CB Brandon Boykin's 80-yard TD run with 8:39 to go in the first quarter was the first score on offense of his career. It also marked the first time a Georgia defensive player scored a TD on offense since CB Branden Smith did against Tennessee Tech in 2009… Seven true freshmen—Crowell, Herrera, cornerbacks Damian Swann, Nick Marshall and Chris Sanders, S Corey Moore and receiver Malcolm Mitchell saw playing time in the first half… Backup offensive guard Kolton Houston, a redshirt freshman, was not on the dress list and did not play against Boise State.
