United States Olympic Committee (USOC) chairman Larry Probst will step down at the end of the year, announced the organization, which has faced criticism of its handling of sexual abuse scandals.
Probst will be replaced by Susanne Lyons, an independent USOC board member who until last month served as the USOC's acting chief executive officer.
Lyons, who will begin a four-year term as chairman on January 1, 2019, was replaced as USOC chief executive last month by Sarah Hirshland.
"We will do everything to regain the trust of our entire athlete community, especially those survivors of recent sexual abuse scandals," Lyons said.
Probst served three four-year terms in the position, helping improve relations with the International Olympic Committee, and praised Hirshland and Lyons and the leadership changeover.
"I think change is good and I think there are some areas where we need change going forward," Lyons said. "That has to start with the board and with Sarah."
