Muhammad Ali's refusal to be inducted into the U.S. Army on April 28, 1967, had a significant impact on his boxing career. Here are the key effects:

1. Stripped of Titles: Ali was stripped of his heavyweight title as a result of his refusal. He was also banned from boxing for several years during what could have been the prime of his career.

2. Legal Consequences: He faced legal battles, including being convicted of draft evasion. His boxing license was suspended, and he was fined, although he stayed out of prison during the appeals process.

3. Loss of Fighting Years: Ali lost about three and a half years of his boxing career (from 1967 to 1970) due to the ban on his professional activity.

4. Public and Financial Strain: His stance was controversial, and he faced both public criticism and support. Financially, the lost years meant missing out on potential earnings from fights.

Despite the setbacks, Ali's refusal became a defining moment in his life, illustrating his commitment to his principles and contributing to his legacy beyond the boxing ring.
