Joe Calzaghe fight record is 46-0; every single one of his fights from his 1993 debut through to 2008 ended in a win, and even now at 54, in 2026, people are still offering him money to fight again, and he still keeps saying no.
Boxing throws the word “undefeated” around a bit too easily sometimes; usually there’s some soft opponent buried in there somewhere padding things out. That’s not really the case with Calzaghe. Look at his fight record and you’ll see he won all 46 of his professional bouts, moved up a full weight class near the end, and still walked away with world titles in both divisions he fought in.
