After an ultimatum by the U.S. Olympic Committee, USA Gymnastics said Friday it will comply with a demand for its entire board of directors to resign within a week over handling of the Larry Nassar sex-abuse scandal.

The three top members of the board resigned earlier in the week, months after President Steve Penny stepped aside under pressure. But that didn't quell criticism, and the Olympic Committee called for bigger changes.

In a statement late Thursday, the committee outlined six conditions that USA Gymnastics must meet or be decertified as the national governing board for the sport.

"While the USOC encourages USAG to think and act broadly on reforming its culture, we also believe that reform must start with an entirely new board," CEO Scott Blackmun wrote.
