LUBBOCK, Texas -- Texas Tech University found minor policy violations in a review of merchandise transactions between Tim Knight, an athletic department official and son of coach Bob Knight, and a store he owned in Indiana.

``There were mistakes made,'' athletic director Gerald Myers said in a news release Thursday. ``Laws were not broken and the only intent by individuals involved was to market Texas Tech and our basketball program. All of us at the university share responsibility for these mistakes.''

The merchandise, about 900 miniature basketballs, some caps and media guides, were shipped to The General's Store in Indianapolis. The store, which opened while Bob Knight was the coach at Indiana, was owned by Tim Knight and operated by his mother Nancy Knight.

In return, the Indiana store sent Tim Knight pictures of Bob Knight and other items to be sold at a store that Tim Knight oversaw on the Tech campus.

The trading began in mid-October. The store closed this spring.

In a letter to Tech President David Schmidly, Frances E. Grogan, the university's system auditor, wrote that some procedures used violated school policy prohibiting extension of state credit.

Grogan recommended to Schimidly that athletic department management review university requirements for invoicing, bidding and contracting with personnel.

Myers said the department needs to ``do a better job making sure everyone understands university policy.''

Tim Knight, now associate athletic director of special projects, came from the private sector where the transactions similar to the ones he did at Tech would not have raised concern, Myers said.

Knight, who was an assistant athletic director at the time, was removed from involvement in the Double T Shoppe on April 1 but it was not a result of the media inquiries into the transactions, Myers said. The younger Knight had decided several weeks earlier that he should relinquish his Double T Shoppe responsibilities as it was taking too much time away from his responsibilities as associate athletic director.
