Indiana announced Sunday that the school's basketball staff exceeded NCAA limits on calls to recruits during the past year — a period during which Sampson was prohibited from off-campus recruiting because of excessive recruiting calls when he was coaching at Oklahoma.

The new violations happened on about 10 occasions when an IU assistant coach started three-way calls that connected Sampson into an ongoing recruiting conversation with recruits, their parents or coaches, school officials said.

"We determined that the impermissible calls occurred because some staff members did not fully comply with the sanctions they were operating under," IU athletic director Rick Greenspan said in a school statement. "We are addressing the problem, and we are voluntarily extending these limitations on recruiting for another season to ensure that the full effect of NCAA restrictions or recruiting is realized."

Sampson, who is entering his second year leading the Hoosiers, and Greenspan were scheduled to discuss the sanctions with reporters Sunday afternoon.
