San Diego State officials announced Tuesday that the NCAA has informed them it has "concluded its inquiry" into allegations of rules violations by the Aztecs men's basketball program and now considers the matter closed.

In a release, San Diego State said it received notification from the NCAA informing it that "based on the available information, the allegations were not substantiated and it does not appear there is need for further inquiry."

CBS Sports reported in September that SDSU's program, according to multiple sources, was being investigated for potential rules violations. SDSU subsequently responded by stating the NCAA had not "commenced a formal investigation" -- although sources again confirmed to CBS Sports that investigators were already looking into allegations of rules violations. After CBS Sports' initial report, SDSU officials acknowledged they did "work hand-in-hand with the NCAA" until the NCAA closed the case after several months.

"The enforcement staff appreciates the institution's cooperation related to this matter," the NCAA told San Diego State.

"I am pleased that this confirms what I and our administration have known all along, that as a staff, we take great pride in representing San Diego State University and the men's basketball program, and conducting this program with the highest integrity," SDSU coach Steve Fisher said. "These types of allegations are not uncommon in major college athletics. What is uncommon is that they ever come out in the public. I appreciate the NCAA's efforts to thoroughly look into this matter as well as the conclusion that there was no wrongdoing."
