Two former Oklahoma athletes have been convicted by a federal jury of obtaining cocaine for former Sooners quarterback Charles Thompson to sell.

After three hours of deliberations, a jury in Oklahoma City convicted John Green, 25, of Detroit and Lamont Harris, 23, of Dallas. They were accused of supplying 17 grams of cocaine to Thompson, who sold it to an undercover FBI agent in January 1989. He is serving a two-year prison sentence in connection with that sale.

Green and Harris were found guilty of conspiracy to distribute cocaine, as well as cocaine distribution. Harris also was found guilty of using a telephone to facilitate a drug transaction.

Both face up to 40 years in prison, although prosecutors said sentences likely would be similar to Thompson's. U.S. District Judge Ralph Thompson denied bond for both pending formal sentencing. . . .

A nine-month investigation into alleged financial wrongdoing at Prairie View A&M has resulted in the arrests of five persons, including the woman chosen to head the U.S. track team for the 1992 Olympics, according to a special prosecutor in Hempstead, Tex.

The felony and misdemeanor charges range from official misconduct to theft, bribery and forgery, and stem from allegations that at least $40,000 and possibly more than $100,000 may be missing from the athletic department's coffers, prosecutor A.M. "Buddy" McCaig said.

Four persons were arrested Tuesday; the fifth, former golf coach Bartolo Perez, was taken into custody yesterday. On Tuesday, Prairie View Athletic Director Barbara Jacket, former athletic director Brutus Jackson, men's track coach Hoover J. Wright and Harris County deputy constable James B. "Tiny" Andrews were arrested. All have been released after posting bond.

Jacket, 54, of Prairie View, is accused of altering restaurant receipts to increase the amount the university reimbursed her. The charges include two counts of official misconduct and 13 counts of securing execution of a document by deception, involving travel vouchers from mid-1987 through early 1989.

She recently was chosen by The Athletics Congress to head the U.S. women's track team for the 1992 Olympics and has been at the university since 1964. . . .

The University of Miami has announced it will abolish athletic dormitories in an effort to integrate athletes more fully into campus life.

Most athletes said they opposed mandatory "mainstreaming," and most coaches said they preferred the athletic dorm system because it makes it easier to monitor their teams and players' study habits.

However, Miami President Edward T. Foote reversed an earlier decision to stay with the status quo, saying the athletes would benefit from interaction with their classmates.
