A former University of Kansas athletics official has admitted in court that he knew other school officials were involved in a lucrative ticket-scalping racket but concealed the crime and didn't alert authorities.

Former assistant director of ticket operations Jason Jeffries pleaded guilty Wednesday in federal court in Wichita to one count of misprision of a felony. He remains free on his own recognizance and was due back in court for sentencing Sept. 29.

The university has accused Jeffries and five other former employees of scheming to sell at least $1 million in basketball and football tickets to brokers.

Jeffries' attorney said outside the courtroom that Jeffries has accepted his responsibility and has nothing to hide.
