Miami-Florida has been accused of a "lack of institutional control" violation, according to the Miami Herald.

"The University of Miami deeply regrets and takes full responsibility for those NCAA violations that are based on fact and are corroborated by multiple individuals and/or documentation," Miami president Donna Shalala said in a statement Tuesday night. "We have already self-imposed a bowl ban for an unprecedented two-year period, forfeited the opportunity to participate in an ACC championship game, and withheld student-athletes from competition.

"Over the two and a half years since the University of Miami first contacted the NCAA enforcement staff about allegations of rules violations, the NCAA interviewed dozens of witnesses, including current and former Miami employees and student-athletes, and received thousands of requested documents and emails from the University.

"Yet despite our efforts to aid the investigation, the NCAA acknowledged on February 18, 2013 that it violated its own policies and procedures in an attempt to validate the allegations made by a convicted felon. Many of the allegations included in the Notice of Allegations remain unsubstantiated."

The school provided the following information about the investigation itself:

- Many of the charges brought forth are based on the word of a man who made a fortune by lying. The NCAA enforcement staff acknowledged to the University that if Nevin Shapiro, a convicted con man, said something more than once, it considered the allegation "corroborated" -- an argument which is both ludicrous and counter to legal practice.

- Most of the sensationalized media accounts of Shapiro's claims are found nowhere in the Notice of Allegations. Despite their efforts over two and a half years, the NCAA enforcement staff could not find evidence of prostitution, expensive cars for players, expensive dinners paid for by boosters, player bounty payments, rampant alcohol and drug use, or the alleged hundreds of thousands of dollars in cash and gifts given to student-athletes, as reported in the media. The fabricated story played well - the facts did not.

- The NCAA enforcement staff failed, even after repeated requests, to interview many essential witnesses of great integrity who could have provided first-hand testimony, including, unbelievably, Paul Dee, who has since passed away, but who served as Miami Athletic Director during many of the years that violations were alleged to have occurred. How could a supposedly thorough and fair investigation not even include the Director of Athletics?

- Finally, we believe the NCAA was responsible for damaging leaks of unsubstantiated allegations over the course of the investigation. Let me be clear again: for any rule violation - substantiated and proven with facts - that the University, its employees, or student-athletes committed, we have been and should be held accountable. We have worked hard to improve our compliance oversight, and we have already self- imposed harsh sanctions. We deeply regret any violations, but we have suffered enough.

The next step in the process is the sanctions phase, where Miami's penalties will be decided.

Miami's football program had come under fire after reports surfaced that players were given gifts and extra benefits from Shapiro, now serving jail time for running an alleged Ponzi scheme.

The NCAA's investigation began in August 2011.

The process dragged on and the NCAA acknowledged that some mistakes were made by its own enforcement department. According to the external review, staff enforcement members knowingly circumvented legal advice to engage Shapiro's criminal defense attorney; violated the internal NCAA policy of legal counsel only being retained and monitored by the legal staff; paid insufficient attention to the concern that engaging the criminal defense attorney could constitute an inappropriate manipulation of the bankruptcy process; and did not sufficiently consider the membership's understanding about the limits of the enforcement staff's investigative powers.

The NCAA said the information gained through the bankruptcy proceedings or other evidence derived from that process will not be used in the Miami investigative record.
