It didn't take college football long to register this season's first major upset as defending national champion Notre dame was humbled, 3-0, at South Bend by Missouri Saturday in the first full weekend of play.

Warren Powers, Missouri's first-year coach, has a tough schedule, so there won't be much time to gloat over the upset of the Irish.

Next week, in its home opener, Missouri challenges No. 1 ranked Alabama. Later the Tigers have games against Oklahoma, Iowa State, Colorado and Nebraska, all nationally ranked teams.

"Sure it's a tough schedule," said Powers, who coached at Washington State last year. "But those hotshot teams have to play us, too, and we showed against Notre Dame that we aren't going to lay down for anybody, the national champions, the No. 1 team, or anybody."

Powers shelved the archiac offense the Tigers used in a 4-7 season last year and put in a fancy veer offense that is both exciting and effective.

Things went even smoother for the Tigers because Notre Dame could not handle Missouri's strong defense. It stopped the Irish four times inside the 30 in the final period and twice inside the 10-yard line.

The only points of the afternoon came on a 33-yard field goal by Jeff Brockhaus with 12:50 to play.

Notre Dame Coach Dan Devine was kicking himself for not going for a field goal some of those times the Irish were so close.

"I guess I forgot that field goals still win football games," he said.

It seems early for teams to be playing important conference games, but Washington and UCLA did just that in Seattle in the first ever pacific-10 game. The Bruins blocked a Washington punt in the end zone, recovered it for a touchdown and held on for a 10-7 victory in heavy rain.

The victory gives the Bruins the early inside track to the Rose Bowl.

The Pac-10's other nationally ranked team, Southern California, beat Texas Tech, 17-9, in a non-conference game. Junion tailback Charles White ran for 156 yards and probably will become the Trojans' all-time leading rusher this season, passing Anthony Davis, Mike Garret and O. J. Simpson.

Oklahoma, another contender for the national championship, fumbled eight times but managed to recover four and hold off Stanford, 35-29.

Stanford quarterback Steve Dils completed 32 of 49 passes for 299 yards, but he threw two interceptions late in the game.

Texas A&M showed what it can do without the wishbone as it rolled to a 37-10 victory over Kansas in Lawrence. Tailback Curtis Dickey flashed for 128 yards and sophomore quarterback Mike Moseley completed seven of 11 passes.

Third-ranked Penn State, determined not to show too much before next Saturday's clash with Ohio State in Columbus, got four field goals from Matt Bahr and beat Rutgers, 26-10, for its second straight victory.

Locally, Maryland got off on the right track with a 31-7 victory ofer Tulane at Byrd Stadium.

Quarterback Tim O'Hare completed seven of 11 passes and Steve Atkins ran for 123 yards.

Second-string Maryland linebacker Pete Haley Jr. sustained a cracked vertebrae in his neck in the game and was taken to Leland Memorial Hospital.

The injury is not serious and he is expected to be out of the hospital in one or two days. Haley did not suffer any paralysis and walked off the field after the injury. He later felt pain in his arm, however, and was taken to the hospital on a stretcher.

Haley, who transferred to Maryland from Tennessee, was a walk-on and was to sign a Maryland scholarship today.

Virginia's miseries continued as the Cavaliers were shut out, 14-0, by Wake Forest.

Bill Dooley will have to wait at least another week for his first victory at Virginia Tech. The Gobblers rushed to a 21-0 lead over visiting Tulsa but ended up losing, 35-33. Tech tailback Kenny Lewis did rush for 186 yards, however.

Among other area teams, University of D.C. beat St. Vincent, 8-0, and Bowie State beat St. Paul's, 13-0.

Navy and Howard begin their seasons next week.
