John Chadima, a top lieutenant to University of Wisconsin athletic director Barry Alvarez, has resigned amid an allegation of misconduct.
The alleged incident took place while the UW football team was in Los Angeles to play in the Rose Bowl, say two sources close to the football program. One source asked to remain anonymous because of his relationship to Chadima and the other asked to remain unidentified for job reasons.
Chadima, a senior associate athletic director who oversaw capital projects and was the sports administrator for football, men's and women's golf and wrestling, resigned Friday after being placed on administrative leave by UW-Madison interim chancellor David Ward.
"We take any and all such allegations seriously," Vince Sweeney, the UW vice chancellor for university relations, said Saturday. "We've responded in what we feel is an appropriate manner."
Sweeney said a campus review of the matter is ongoing. He declined to say if Chadima was forced to step down.
Chadima's school-issued cellphone was disconnected, and he didn't immediately return calls to his home.
UW-Madison Police Sgt. Cherise Caradine told The Associated Press she wasn't immediately aware of any investigation involving Chadima. His name did not show up in a search of online court records Saturday.
Alvarez is expected to return to Madison early from a planned stay at his Florida home in Naples.
Chadima is a University of Iowa graduate who came to UW when Alvarez was hired as football coach in 1990. Chadima served as director of football operations from 1990 to 1997 and 2000 to 2003 with a stint in between as an assistant director of facilities and events.
When Alvarez succeeded Pat Richter as athletic director in 2004, he added Chadima to his senior staff and gradually gave him more responsibilities. The biggest involved the $109 million renovation of Camp Randall Stadium. He was overseeing two major projects - LaBahn Arena for men's and women's hockey and swimming and the Athletic Performance Center.
During bowl trips, Chadima is known for hosting a party for the unsung members of the UW football entourage, including equipment staffers and managers. It's not known if the allegation is related to the latest get-together.
In addition to Chadima's departure, the athletic department is dealing with massive turnover on football coach Bret Bielema's staff after a 45-38 loss to Oregon in the Rose Bowl.
Five assistant coaches have left, including four to Pittsburgh where former offensive coordinator Paul Chryst was hired as coach last month.
