The miseries continued yesterday for the second-ranked Miami Hurricanes when offensive tackle Matt Patchan, the team's top blocker, suffered a sprained knee that could keep him out of the national championship Orange Bowl game with No. 1 Oklahoma.

Last Thursday, Miami lost its other starting offensive tackle, John O'Neill, along with star linebacker George Mira Jr., when they failed an NCAA-administered drug test and were suspended from the Orange Bowl.

In addition, Scott Provin, a season-long starter at guard who will now switch to tackle, missed Sunday's practice with stomach problems. He is expected to work out today.

"Right now, we've got about six healthy offensive linemen total for the ball game, with three new starters when you consider that Provin will be starting at tackle for the first time this year," Coach Jimmy Johnson said.

"For having an offensive line that only gave up a minimum amount of sacks {13} all year long, to have to go in to play a defensive team like Oklahoma with three new starters is a concern . . . We just need to make sure that the new faces come to the front and practice well this week." . . .

Texas starting cornerback Tony Griffin failed NCAA drug tests and has been declared ineligible for the Bluebonnet Bowl football game Thursday night, Longhorns Coach David McWilliams announced yesterday.

Griffin, who earlier said he did not want to play in the New Year's Eve game against Pittsburgh at the Astrodome, was the only Longhorn who did not pass the tests, McWilliams said.

"The student athlete in question was found in violation of the NCAA eligibility rules and has been declared ineligible for postseason competition," McWilliams said in a statement. McWilliams declined to say what kind of substances were involved.

Griffin, a 5-foot-9, 170-pound senior from Austin, will be replaced in the starting lineup by sophomore Fred Stromile . . .

Five Southern California players, including four allegedly involved in a brawl outside a movie theater on the opening night of Eddie Murphy's film, "Raw," will be able to play in the Rose Bowl New Year's Day.

Coach Larry Smith said starting flanker Randy Tanner, defensive backs Tracy Butts and Reggie Smith, and reserve wide receiver Gene Arrington will not be suspended for the Rose Bowl against Michigan State.

Tanner, Butts and Smith were charged with unlawful assembly Dec. 18 outside a West Los Angeles theater and Arrington was arrested the same night for allegedly scratching a police officer.

Reserve safety Jeff Maree, scheduled to appear Jan. 5 in Rio Hondo Municipal Court for charges relating to an incident involving his girlfriend, will not be suspended for the game, Smith said . . .

Iowa has shuffled its lineup for Wednesday's Holiday Bowl to replace two defensive starters who were left behind for disciplinary reasons.

Defensive coordinator Bill Brashier said Jay Hess and Sean Ridley will replace free safety Dwight Sistrunk and defensive end Joe Mott when the Hawkeyes meet Wyoming at San Diego Jack Murphy Stadium.
