Sony Michel ran for 155 yards and three touchdowns to highlight a big day for freshmen in No. 13 Georgia's 66-0 win over Troy on Saturday.

Michel, playing behind Todd Gurley, had a 75-yard gain to set up his second touchdown.

Among other standout freshmen for Georgia (2-1) were receiver Isaiah McKenzie, who scored on a 52-yard punt return, and Bryce Ramsey, who threw his first career touchdown pass.

Dontreal Pruitt started at quarterback for Troy (0-4) as Brandon Silvers was held out after leaving last week's loss to Abilene Christian with a concussion. The Trojans' last 0-4 start was in 1982.

The Bulldogs posted their highest scoring game since a 70-6 win over Northeast Louisiana in 1994 and their most lopsided victory since beating The Citadel 76-0 in 1958.

Troy finished with only 216 yards, including 68 on its first possession. The Trojans held the ball for 12 plays on the opening drive, but it ended when Ryan Kay was wide right on a 26-yard field goal attempt.

Pruitt completed 16 of 27 passes for 158 yards with an interception.

Georgia freshman tailback Nick Chubb had four carries for 10 yards less than a week after surgery on his broken left thumb. He wore a big cast on the hand.

Keith Marshall, whose 2013 season ended with right knee surgery, left the game after taking a hit to the same knee late in the third quarter.

Gurley was pulled quickly as the Bulldogs built a big early lead. He carried the ball on Georgia's first four plays, including a 48-yard run, and finished with 73 yards on only six carries.

Georgia led 45-0 at halftime.

The Bulldogs pushed the lead to 52-0 on Hutson Mason's 10-yard touchdown pass to Michael Bennett, who also had a 6-yard scoring catch from Ramsey. Mason completed 8 of 11 passes for 97 yards and two touchdowns.

Georgia's third quarterback, Faton Bauta, had scoring runs of 7 and 1 yards in the fourth quarter.

Troy quarterbacks had a streak of 176 consecutive passes without an interception end in the third quarter. Troy's hopes for its first points ended when Georgia freshman safety Tramel Terry intercepted a pass from Pruitt in the end zone.

Georgia lost two safeties early in the game. J.J. Green was ejected after drawing a targeting penalty on his helmet-to-helmet hit on receiver Chandler Worthy on the third play. Quincy Mauger was escorted to the locker room with an apparent right shoulder injury later in the same drive.
