ANN ARBOR, Mich. -- The NCAA has concluded that Michigan coach Rich Rodriguez did not fail to promote an atmosphere of compliance, a previous allegation that the school challenged, a source close to the situation said Wednesday night.

The NCAA will reveal its findings as early as Thursday, the source said. The NCAA will also announce if Michigan's self-imposed penalties for admitted excessive football-related hours and excessive coaches were acceptable.

While the source did not reveal specifics of those findings, the person said the results were "positive news for Michigan football."

The program, however, will be hit with another year of probation, a source with knowledge of the situation said, according to the Detroit News.

The NCAA accused Michigan of five major rules violations related to exceeding practice and workout time in the wake of a Detroit Free Press report last year. The report led to investigations by both the school and the NCAA.

The school accepted responsibility for four of the allegations, but Michigan vigorously challenged a charge that Rodriguez failed to promote an atmosphere of compliance with NCAA rules during an August hearing in Seattle.

Michigan announced in May that its self-imposed sanctions included probation for two years and reducing training time by 130 hours over two years -- doubling the amount of time the Wolverines exceeded NCAA rules.

The school also reprimanded seven people, including Rodriguez.
