KNOXVILLE, Tenn. — Georgia's national title hopes kept shrinking as its injury list kept growing. Then Aaron Murray and Marshall Morgan came to the rescue and saved the sixth-ranked Bulldogs' championship aspirations. Morgan kicked a 42-yard field goal in overtime after Murray threw a game-tying touchdown pass with 5 seconds remaining in regulation Saturday as Georgia overcame a flurry of injuries in a 34-31 victory at Tennessee.
