ATHENS— This was supposed to be the night Aaron Murray was celebrated for the toughness that helped him shine as one of the most prolific quarterbacks in SEC history. Instead, Murray had to be carried off the field with a knee injury that coach Mark Richt said sapped much of the joy out of Georgia's lopsided win over Kentucky. Murray threw four first-half touchdown passes before hurting his left knee, leaving backup Hutson Mason to play the second half in Georgia's 59-17 rout of Kentucky on Saturday night.
