10 Undefeated Boxing Streaks You Need To Know About

6. Edwin Valero - 27-0, 27 KOs (2002-2010)

Lightweight Valero didn't wait around before making a name for himself. The Venezuelan, to this day, is the only fighter in history to have a 100% knockout record from anyone who has fought over 25 fights. That record speaks for itself. On April 18, 2010, Valero was arrested after police found the body of his 24-year-old wife in a hotel. Valero was considered a suspect and was taken to jail after allegedly admitting to hotel security and police that he had murdered her. The following day he was found hanging in his prison cell.
