Jon Vaughn, the nation's rushing leader, ran for 288 yards and three touchdowns yesterday as seventh-ranked Michigan ran over UCLA, 38-15, in Ann Arbor, Mich.

Vaughn, a sophomore, became the first back in Michigan history to rush for more than 200 yards in consecutive games. He had 201 yards in the Wolverines' 28-24 loss to top-ranked Notre Dame last week.

Vaughn's third touchdown was his most spectacular: He was grabbed at the line by Roman Phifer but shook him off, broke up the middle and dashed 63 yards. His first run from scrimmage yesterday could have been a sign of things to come: He went 43 yards over right guard. No one has rushed for more yards against UCLA (1-2); Marcus Allen had 219 yards against the Bruins in 1981.

Nebraska 56, Minnesota 0: Mickey Joseph ran for two touchdowns and passed for two more as the eighth-ranked Cornhuskers (3-0) built a 42-0 halftime lead -- piling up 379 of their 564 total yards in offense -- in dismantling the Golden Gophers (1-2) in Lincoln, Neb.

Joseph, making his second start in place of injured Mike Grant, ran four yards for his first score in the first quarter. He ran one yard for another touchdown and threw 27 yards to Jon Bostick and one yard to Chris Garrett for touchdowns in a 28-point second quarter.

Oklahoma 52, Tulsa 10: In Norman, Okla., two quick touchdown passes from Steve Collins to Artie Guess gave the pass-happy No. 11 Sooners an early lead that never was threatened by the Hurricane (1-3).

Oklahoma (3-0) threw 25 passes, six short of the school record set in 1938, and its 12 completions were three short of the school mark set three times. Collins completed eight of 19 for 165 yards before sitting out midway through the third quarter.

Iowa 45, Iowa State 35: Quarterback Matt Rodgers ignited a 21-point third quarter with a five-yard touchdown run and Lew Montgomery scored twice, leading the Hawkeyes (2-0) in Iowa City.

Temple 24, Wisconsin 18: In Madison, Wis., Conrad Swanson ran 32 yards for a fourth-quarter touchdown and Bob Wright kicked a 39-yard field goal in the closing minutes as the Owls (2-2), playing their first Big Ten opponent in 38 years, rallied past the Badgers (1-2).

Purdue 41, Indiana St. 13: In West Lafayette, Ind., quarterback Eric Hunter passed for 291 yards and four touchdowns for the Boilermakers (1-1). Indiana State, a Division I-AA school, is 1-3.

Indiana 58, Missouri 7: In Bloomington, Ind., Vaughn Dunbar raced 80 yards for Indiana's longest touchdown run since 1977 and Rob Turner scored three touchdowns as the Hoosiers (2-0) broke the school record for points at Memorial Stadium (52 against Navy in 1986).
