The NCAA sent a notice of allegations to Indiana University last Friday detailing major violations in its men's basketball program, multiple sources told ESPN.com.
Larry MacIntyre, assistant vice president for university communications at Indiana University, confirmed to ESPN.com that the school did receive documentation from the NCAA last week.
The Associated Press reported on Tuesday night that the school will make the allegations public on Wednesday. University trustees president Stephen Ferguson told AP that school officials this week reviewed the report, but that the NCAA is not expected to make its ruling until this summer.
"There won't be a hearing till this June," Ferguson told AP. "It's just been reviewed, and I think everyone is analyzing it now."
MacIntyre said he was unable to provide any more information. But MacIntyre said he was working on providing a copy of the documentation after ESPN.com requested one through the Freedom of Information Act.
But ESPN.com has learned over the last week that the NCAA uncovered new information since Indiana self-reported violations under second-year head coach Kelvin Sampson in October.
Sampson had been sanctioned after making impermissible phone calls while he was the coach at Oklahoma. Indiana then revealed more bad calls while Sampson was at IU.
Multiple sources told ESPN.com that the NCAA was looking into whether Sampson did not tell the truth about those calls, resulting in the allegations of major violations.
This new information that helped result in a major violations tag could leave the Hoosiers' season, and Sampson's career, under a cloud of uncertainty.
ESPN.com made multiple efforts to reach Indiana athletic director Rick Greenspan over the past week and he never returned calls. Sampson didn't return a message Tuesday.
Indiana (20-3, No. 12 ESPN/USA Today, No. 13 AP) will have 90 days to respond to the letter. The committee on infractions has a hearing in April, but because of the 90-day window the hearing isn't expected to take place until the June meeting. That means Indiana might not have closure on the matter until late into the summer.
"The report came out in October, the university filed its response and there's really not been anything happening [on the board] in the last five months," Ferguson told AP. "There have not been any discussions."
A postseason ban for the Hoosiers would come into play only if IU decided to self-impose such a measure since the committee on infractions won't meet until June. According to multiple sources, a postseason ban would only occur if there were an issue with the eligibility of any current student athletes, which ESPN.com has been told isn't an issue yet.
The NCAA investigation came after Indiana made an announcement in October that Sampson had made 100 impermissible phone calls while he was on probation for illicit calls he made while he was the coach at Oklahoma from 2000 to 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 at IU. He was also banned from making calls and going off campus to recruit for a calendar year. He wasn't 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 the staff. In October, Indiana made public that former assistant Rob Senderoff initiated three-way calls. During the October news conference, Indiana said that Sampson said he was unaware he was participating on a three-way call. Senderoff, who was forced to resign, said he didn't let Sampson know he was on a three-way call, either. Prior to being forced out, Senderoff was told he couldn't recruit off campus for a year or make a phone call. The same restriction was put on Dan Dakich, who has since been moved up to an assistant 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.
