As an amateur, Shavers won the 1969 National AAU heavyweight title before launching his professional career, where he would contend for two world heavyweight championships, losing out both times to legendary boxer Muhammad Ali in 1977 and Larry Holmes in 1979.

"Earnie was always good to me," Holmes told Ring.com on Friday. "He came here to Easton (Pennsylvania) a lot of times. If I needed something, he’d come — no charge or nothing. He came to a golf tournament here and everyone liked him. Earnie was a good guy, and he never complained about anything."

"Earnie came to my house a lot over the years and we’d laugh and talk," he said of their friendship. "He’d say, ‘I had you, Larry!’ He hit me a couple of times, knocked me down and stuff. I told him, ‘You hit too damn hard!’ I’ve said it before, he knocked me out with that shot and when I hit the ground I woke up. Not long ago, I told him that story."

"I tell you what, when Earnie Shavers hit Muhammad Ali, he felt it," Holmes told the outlet. "I always told Earnie that Ali was messed up and slow [because of the punishment he took in that fight]. Earnie would say, ‘I didn’t do that, everyone else did it.’ I told him, ‘Nobody else hit like you, Earnie!’"
