"The USOC is deeply saddened to hear that the sports world has lost one of its most iconic figures in Muhammad Ali. As we reflect on his accomplishments and victories, we are proud to call Ali not only a member of Team USA, but an Olympic champion. With unparalleled grit and determination, he left a legacy that will continue to inspire generations of Americans for years to come. Our thoughts and prayers are with his family and friends during this difficult time."
