Unranked Arkansas, led by halfback Gary Anderson and quarterback Tom Jones, shocked No. 1 Texas today with a 42-11 Southwest Conference victory.

It was the second-worst defeat Texas had received from Arkansas in the 63 years the schools have played each other. The Razorbacks won, 42-6, in 1938.

The Longhorns joined Michigan, Notre Dame and Southern California, all of which had been unbeaten and ranked No. 1 in The Associated Press poll before being upset.

"We were ready and we were eager," said Texas Coach Fred Akers. "I just can't explain it."

His all-America tackle, Kenneth Sims, noting the four interceptions and three lost fumbles by teammates, said, "We just kept pumping air in them all day . . . just kept giving them everything."

Said Arkansas Coach Lou Holtz, "I'm glad we're not playing them again tomorrow."

Arkansas is 5-1 overall, 2-1 in the SWC, while Texas dropped to 4-1, 1-1.

It was Arkansas' first victory over Texas in Fayetteville in 16 years and only the Razorbacks' third victory in 15 games against the Longhorns.

Arkansas recovered an early fumble and turned it into a quick touchdown on Jones' one-yard run and the jittery Longhorns never recovered.

Before Texas got a first down, Arkansas was ahead, 15-0, thanks to a safety on a bad center snap and a five-yard touchdown run by Anderson, his first score this season.

"The key to the game was the way our offensive line dominated their defensive line," said the Razorbacks' Jones.

The teams traded field goals before the Razorbacks scored just before the half on Jones' 19-yard pass to Anderson.

With many in the crowd of 44,031 cheering loudly, Arkansas ran the count to 32-3 on Jones' four-yard run and led, 39-3, at the end of the third period after Darrell Bowles went 19 yards.

Bruce Lahay's 37-yard field goal with 9:32 to play gave Arkansas a 42-3 lead, then Texas scored its only touchdown on Robert Brewer's eight-yard pass to Donnie Little.

Linebacker Jeff Goff was the defensive star for the Razorbacks, recovering a fumble and intercepting a pass that led to touchdowns. He also jarred the ball loose from a receiver on an apparent touchdown pass.

Cornerback Danny Walters had two interceptions in the rout.

This tied the second worst defeat in Texas history. The Longhorns lost, 46-0, to Texas Christian in 1956 and were defeated, 52-13, by Oklahoma in 1973.
