BLOOMINGTON, Ind. -- Indiana basketball coach Kelvin Sampson and his staff violated telephone recruiting restrictions imposed because of his previous violations at Oklahoma, then lied about it to the school and NCAA investigators, according to an NCAA report released Wednesday.
The NCAA listed five major violations against Sampson, saying he gave "false or misleading information" to investigators.
Sampson "failed to deport himself ... with the generally recognized high standard of honesty" and "failed to promote an atmosphere for compliance within the men's basketball program," according to the report.
Athletic director Rick Greenspan promised the university would cooperate with all NCAA requests.
"We are extremely disappointed in these new allegations regarding coach Sampson," Greenspan said in a statement. "To say the least, we view these allegations with grave concern."

Major violations of NCAA rules can carry punishments including postseason ineligibility. Indiana already had self-reported violations under Sampson in October, but the new discovery could put the Hoosiers' season, and Sampson's career, under a cloud of uncertainty.
The Hoosiers have had no NCAA major violations since 1960.
Indiana (20-3, No. 12 ESPN/USA Today, No. 13 AP) has until May 8 to provide a written response, but the matter could simmer late into the summer. The committee on infractions has a hearing in April, but because of the allotted 90-day window for Indiana to respond, the hearing is not expected to take place until the committee's planned June meeting.
Sampson did not return a message left for him Tuesday by ESPN.com.
We are extremely disappointed in these new allegations regarding coach Sampson. To say the least, we view these allegations with grave concern.
-- Rick Greenspan, IU's AD
A postseason ban for the Hoosiers would come into play only if IU decides to self-impose such a measure. Multiple sources told ESPN.com that a postseason ban would occur only if there were an issue with the eligibility of any current student-athletes. ESPN.com has been told this isn't the case at this point.
At Sampson's introductory news conference at Indiana two years ago, then-president Adam Herbert said, "I am fully convinced that he will elevate the program to what you expect. ... He has made clear our players will do well academically and graduate and that he will comply fully with NCAA regulations."
Among the allegations cited in the NCAA's report:
• Sampson, assistant coach Jeff Meyer and former assistant Rob Senderoff failed to comply with sanctions imposed on Sampson for impermissible recruiting calls he made while he was the head coach at Oklahoma. Sampson was under such sanctions when he was hired to coach the Hoosiers in March 2006.
Sampson and Senderoff, who resigned his position Oct. 30, are alleged to have jointly participated in telephone calls at a time when Sampson was prohibited from being present or taking part when staff members made recruiting calls. Senderoff and Meyer are alleged to have made about 100 calls that exceeded the sanction limits.
• Senderoff and Meyer placed "at least 25 telephone calls" to nine potential recruits that exceeded NCAA limits even if no sanctions had been in place.
• Sampson "acted contrary to the NCAA principles of ethical conduct when he knowingly violated recruiting restrictions imposed by the NCAA Committee on Infractions."
• Sampson and Meyer engaged in an impermissible recruiting contact during a two-day sports camp held at Assembly Hall last June 30 and July 1, and that Meyer provided the potential recruit with an impermissible benefit -- at least one T-shirt and drawstring backpack.
The NCAA launched its investigation after Indiana announced in October that Sampson had made 100 impermissible phone calls while he was on probation for illicit calls made while he was the coach at Oklahoma from 2000-2006. During that time, he made 577 impermissible calls.
Sampson was penalized by Oklahoma by not being allowed to travel for recruiting. Indiana imposed the same penalty in his first season as coach. He also was not permitted to make calls or leave campus to recruit for a calendar year. He was not banned from text messaging since it was allowed during that year. But it was during that year that he made the impermissible calls.
Sampson wasn't allowed to take part in three-way calls, originated by anyone on his staff. In October, Indiana made public that Senderoff initiated three-way calls involving Sampson. During the October news conference, Indiana said that Sampson said he was unaware he was participating in three-way calls. Senderoff, who was forced to resign, said he didn't let Sampson know he was on three-way calls, either. Prior to being forced out of his job, Senderoff was told he couldn't recruit off campus for a year or make calls. The same restriction was put on Dan Dakich, who has since been moved up to an assistant's position from director of basketball operations.
Sampson was hit with more penalties by the school, forfeiting a $500,000 raise, and a scholarship was taken away from the team.
Upon his hiring at Indiana in 2006, Sampson said, "It is a little bit embarrassing to stand up here and be asked about NCAA violations, but you also have to realize we're human and we make mistakes. I made a mistake but we've corrected it and moved forward."
In a statement issued through his attorney Wednesday, Meyer said he would continue to cooperate with Indiana and the NCAA.
"I regret that I may have made mistakes that are causing my and IU's conduct to be examined by the NCAA. … I will not comment on this process again before it is completed," Meyer said.
