<p>The Georgia defense made up for another lackluster offensive showing, holding Marshall to seven first downs in the third-ranked Bulldogs' 13-3 victory on Saturday.</p><p>Marshall, which held No. 9 Ohio State to 79 yards rushing in a 24-21 loss last week, shut down a Georgia running game that was without its top two backs. The Bulldogs (3-0) had 41 carries for 146 yards, most coming late in the game.</p><p>After Georgia lost projected starter Kregg Lumpkin to a season-ending knee injury on the first day of practice, Danny Ware suffered a bruised lung in last week's 20-16 win at South Carolina.</p><p>Tyson Browning started Saturday and was mostly ineffective, and Michael Cooper's playing time was limited by a bruised thigh he suffered in the third quarter.</p><p>Freshman Thomas Brown finally began to wear down the Marshall defense as the Bulldogs held the ball most of the fourth quarter. Brown had 18 carries for 81 yards.</p><p>Georgia hopes to have Ware back when it plays host to LSU on Oct. 2.</p><p>Marshall is 0-3 for the first time under ninth-year coach Bob Pruett.</p><p>Held to 13 yards rushing in the first half, Georgia led 10-3 at halftime thanks to an 11-play, 67-yard touchdown drive in the first quarter.</p><p>Cooper vaulted over the line for 3 yards on a fourth-and-1 play from the Marshall 17 to keep the drive alive. Cooper scored from the 2 following a 12-yard pass from David Greene to Fred Gibson.</p><p>Marshall gained 57 yards on its first play from scrimmage when Stan Hill faked a handoff and passed to an open Emanuel Spann. A pass interference call against Georgia cornerback Tim Jennings two plays later pushed Marshall to the 6, but Hill was sacked on third down and Marshall took a 3-0 lead on a 33-yard field goal by Ian O'Connor.</p><p>After Georgia's touchdown drive, the Bulldogs added a 33-yard field goal by Andy Bailey to cap an 82-yard drive that began at their 3. Greene hit freshman A.J. Bryant for 34 yards on the drive.</p><p>Browning lost a fumble that gave Marshall the ball at the Georgia 11 in the third quarter, but the Bulldogs defense kept the Herd off the scoreboard.</p><p>Three carries by Earl Charles gained 9 yards, setting up a fourth-and-1 at the 2. Under pressure, Hill rolled to his right and threw the ball at receiver Brad Bates' feet, ending the drive.</p><p>A 33-yard pass from Greene to tight end Leonard Pope on the first play of the fourth quarter moved Georgia to the Marshall 31 and helped set up a 29-yard field goal by Bailey for a 13-3 Georgia lead.</p><p>Bailey was wide left on a 45-yard field goal midway through the fourth quarter.</p>
