Ann Arbor, MI (Sports Network) - The University of Michigan received a notice of allegations from the NCAA stemming from this past summer's report of potential rules violations within the football program.

Just before the 2009 season began, a report surfaced indicating the football coaching staff violated NCAA rules regarding time limits on off-season workouts and in-season demands.

Six players interviewed by the Detroit Free Press in late August described how the training and practice sessions under Rich Rodriguez far exceeded limits set by the NCAA.

Michigan immediately began its own investigation into the claims, and Rodriguez soon after said he and his staff were clear of any wrongdoing. In late October, however, the school received a letter of inquiry from the NCAA.

School president Mary Sue Coleman and incoming athletic director David Brandon addressed the notice of allegations on Tuesday.

"Intercollegiate athletics is a fundamental feature of the University of Michigan, and we take pride in the integrity of our athletics programs," said Coleman. "We also take full responsibility for knowing and following NCAA rules and thus view the allegations seriously.

"We will make all necessary changes. What we will not do is make excuses. We already are addressing concerns, quickly and head on. All of us -- Coach Rodriguez, David Brandon and I -- are deeply committed to compliance with NCAA rules, and the future of our football program."

Rodriguez has had a shaky start on the field as well, with an 8-16 mark over his first two seasons in charge of one of the most storied programs in college football history. The Wolverines were just 3-9 in his first season and only 5-7 in 2009.

"As head coach, the football program is my responsibility," Rodriguez said Tuesday. "I'll do all I can to carefully monitor all the program's activities. I look forward to working with Dave and the compliance office to ensure there is no question of Michigan football's compliance with NCAA rules. Our philosophy has always been to be very transparent with our programs and to have an open relationship with our compliance office. I need to monitor more closely in the two areas of concern -- and I will."

Brandon, a former Michigan football player who will take over for the retiring Bill Martin next month, outlined some of the NCAA's findings.

The NCAA said that Michigan's non-coaching staff, also known as quality control staff, engaged in coaching activities, which is prohibited.

"We clearly made mistakes in these areas and we have already taken action to prevent any of those mistakes from being repeated," Brandon said Tuesday.

In addition, the NCAA said football players, during the offseason, were sometimes required to participate in as many as 10 hours of activity per week, which exceeded the permissible eight hours.

During the 2008 season, the NCAA said, there were instances when players exceeded the time limit of four hours per day. Some days they went over the limit by an hour and on one occasion by just 20 minutes.

"I have looked into these permissible practice hours issues, and I want to emphasize there were no situations where any student-athlete's welfare was put at risk," Brandon stated.

"Based on my understanding of this situation, I believe a significant reason for these alleged overages is a result of internal confusion over which activities are 'countable' and which are not. We had a lack of clarity around whether time spent in stretching and warm-up activities were 'countable minutes,' and this represents a portion of the discrepancies between the NCAA's findings and our practice routines."

Michigan has until May 24 to file a response to the allegations with the NCAA and will appear before the Committee on Infractions in August.
