Clemson intercepted Georgia quarterback Buck Belue five times and recovered four Bulldog fumbles en route to a 13-3 upset of fourth-ranked Georgia in a nonconference game today, ending the defending national champions' 15-game winning streak.

Georgia's star tailback, Herschel Walker, lost two fumbles, including one at the Clemson 17-yard line early in the game. Walker gained 111 yards rushing on 28 carries; his season average is 164.

"Any time you turn the ball over nine times, you are not a sound offensive football team," said Georgia Coach Vince Dooley.

The Tigers, led on offense by junior quarterback Homer Jordan, made the fumble recoveries and two of the pass interceptions in the first half in building a 10-0 lead.

Clemson, a four-point underdog, dominated the game, but did not score until Jordan threw an eight-yard touchdown pass to Perry Tuttle with 7:13 remaining in the second quarter.

The Tigers increased their lead to 10-0 with 11 seconds remaining in the first half on a 39-yard field goal by Donald Igwebuike, a sophomore from Nigeria. They scored the final points in the game with 14:01 remaining in the fourth quarter when Igwebuike kicked a 29-yard field goal.

Georgia got its only points 3:36 into the third quarter when freshman Kevin Butler kicked a 40-yard field goal.

Georgia appeared headed for the opening score of the game when, with Walker doing most of the running, the Tigers drove from their 45 to the Clemson 13 after recovering a fumble. But Walker lost the ball there with his first fumble and Georgia was to get inside the Clemson 20 only one other time -- when Butler kicked his field goal.

Clemson did not get inside the Georgia 35 in the first quarter. The Tigers did move inside the Bulldog 25 five times in the second quarter, although they came away with only 10 points.

Georgia, which had not lost since the next-to-last game of the 1979 season, appeared to be reviving when it took the second-half kickoff and drove 64 yards before bogging down and settling for a field goal.

The Bulldogs had two long drives in the final quarter when they were depending mainly on the passing of Belue to beat the clock, but Clemsons intercepted three passes in the final 10 minutes. to

Jordan completed 11 of 18 passes for 131 yards and ran 25 times for 59 yards.

Five Clemson players -- Terry Kinard, Billy Davis, Rod McSwain, Tim Childers and Anthony Rose -- intercepted passes by Belue, who completed 12 of 26 throws for 133 yards.
