Arkansas was invited to play in the 1965 Cotton Bowl Classic on January 1, 1965, against the Nebraska Cornhuskers. Arkansas' number-one rated defense was giving up only 5.7 points per game, while No. 7 Nebraska's scoring offense was averaging 24.9 points per contest. Playing before a capacity crowd of 75,504 in Dallas, Arkansas opened the scoring with a field goal by Tom McKnelly in the first quarter. Nebraska took the lead in the second quarter on a one-yard touchdown run by Harry Wilson. Neither team scored in the third quarter. In the fourth quarter, fifth-year quarterback Fred Marshall, whose fumbles had stalled Arkansas in the first half, led the Razorbacks on a nine-play, 80-yard touchdown drive. The drive featured a scramble by Marshall for a first down after it appeared he would be sacked and two passes from Marshall to Jim Lindsey, the second taking the ball to the Nebraska five-yard line. Two plays later, junior tailback Bobby Burnett ran one yard for the game-winning touchdown with less than five minutes remaining in the game. ''Source:
Split national championship and controversy
With its victory in the Cotton Bowl and Alabama's loss to Texas in the Orange Bowl, Arkanas finished the 1964 season as the only major team with an undefeated and untied record. On January 6, 1965, a five-man committee of the Football Writers Association of America selected Arkansas as the winner of Look magazine's Grantland Rice Trophy as the top college football team in the country. Arkansas received four of five first-place votes, with Texas receiving the fifth vote. Alabama did not receive a single vote for first, second, or third place. The five members of the FWAA committee were Si Burick, Dayton Daily News; Fred Russell, Nashville Banner; Blackie Sherrod, Dallas Times Herald; Steve Weller, Buffalo Evening News; and Paul Zimmerman, Los Angeles Times. Arkansas is also recognized as the 1964 national champion by Billingsley Report, College Football Researchers Association, Helms Athletic Foundation, National Championship Foundation, Poling System, Sagarin, and Sagarin. However, the final AP and UPI Coaches polls were released before bowl games were played, and Alabama therefore remained as the national champion in the AP and UPI Coaches' Polls. Because of the controversy, the AP Poll experimented with a voting model that took the final vote to select their champion after the bowl games in the 1965 season. In 1966, the AP Poll went back to taking the final vote at the conclusion of the regular season before finally adopting the post-bowl season model in 1968. The UPI Coaches' Poll adopted the post-bowl season model in 1974 after the controversies surrounding the 1964, 1965, 1970, and 1973 national championships, seasons in which the winner of the Coaches' Poll went on to lose their bowl game.
