Mike Rozier, the 1983 Heisman Trophy-winning running back from Nebraska now in the U.S. Football League, has admitted in a published report to having violated NCAA rules by accepting money in his senior college season.

Sports Illustrated, in its Oct. 22 issue, says Rozier admitted in a tape-recorded interview that he signed with an agent and accepted money during Nebraska's 1983 season. It also says he admitted that, before playing in the Orange Bowl, he entered into a contract with the USFL's Pittsburgh Maulers, for whom he played last spring.

According to the magazine, Rozier said he signed with Los Angeles-based agent Bruce Marks in August 1983, before Nebraska's first game of the season, and that Marks paid him four monthly installments of $600 during the season. Marks is an associate of Mike Trope, but Rozier said he didn't know that then.

Rozier also reportedly told the magazine that, several days before Nebraska's 31-30 loss to Miami that gave the Hurricanes the national championship, he, Marks and Maulers General Manager George Heddleston agreed to terms.

Nebraska Athletic Director Bob Devaney said, "We have no knowledge of what Mike Rozier did or didn't do. It's nothing to do with our athletic program."
