Notre Dame is looking into whether student-athletes, including football and basketball players, violated NCAA rules with comments promoting a local sports talk show on the CBS affiliate here. John Heisler, Notre Dame's senior associate athletic director, said Saturday he became aware of possible violations when contacted Friday afternoon by a reporter for The Journal Gazette of Fort Wayne. Heisler said the school has not seen the spots, promoting "Sports Dogz" on WSBT-TV, so it does not know if it violates NCAA rules. "We're just trying to figure out what this is," he said. "I don't know if we know for sure it's an NCAA violation."
