Mettenberger, a freshman, is competing with fellow freshman Aaron Murray and rising junior Logan Gray for the starting quarterback job this spring. Although spring practice began last Thursday, Georgia's players are on spring break for the next week and will not return to work until March 16.
Georgia's Athletics Association mandates a minimum one-game suspension for any players found guilty of an alcohol-related violation, which could cost Mettenberger a chance to play in the team's opener against Louisiana-Lafayette on Sept. 4.
Mettenberger redshirted last season but offensive coordinator Mike Bobo said the strong-armed quarterback had made impressive strides since arriving in Athens last spring and was contender for the starting job left open following the graduation of Joe Cox. Mettenberger played in high school at nearby Oconee County High School.
