Probst to step down as USOC chairman after a decade

DENVER (AP) — Larry Probst will step down as chairman of the U.S. Olympic Committee at the end of the year, ending a decade-long stay during which he restored the federation's international reputation but will leave it facing as many problems as he inherited on the home front.

Probst will be replaced by Susanne Lyons, who recently finished serving as interim CEO following the resignation of Scott Blackmun in February.

The 68-year-old Probst helped repair fractured international relationships, which ultimately resulted in the U.S. landing the 2028 Summer Olympics in Los Angeles. That victory came after repeated failures, including Chicago's embarrassing bid for the 2016 Games, which came shortly after Probst took over.

Probst has also been at the helm for the USOC's widely criticized response to a mushrooming sex-abuse crisis in Olympic sports, which played a part in Blackmun's departure and has made the USOC a defendant in a number of lawsuits filed by victims.
