CHAMPAIGN-A University of Illinois gymnastics coach who resigned this month for unspecified personal reasons is facing a drunk-driving charge in Wisconsin.

Waukesha County court records indicate that Jon Valdez was charged with operating while under the influence after his Sept. 18 arrest. He’s pleaded not guilty.

Valdez trained U.S. gymnasts at the Beijing Olympics, and he resigned from the Illinois men’s team Oct. 17.

Illinois head coach Yoshi Hayasaki (hy-yuh-SAH’-kee) says Valdez’s resignation wasn’t related to the arrest, but he referred questions to Assistant Athletic Director Kent Brown, who declined comment.

No telephone listing could be found for Valdez. A woman who answered the door at his Urbana home Tuesday said he wasn’t there.
