Fighters who Quit

[Master]

All time greatest quitters:
1. Acelino Freitas (vs Juan Diaz and Chico Corrales)
2. James Buster Douglas
3. Charlie Zelenoff
4. Oliver McCall
5. Bruce Seldon
6. Mike Tyson
7. Vitali Klitschko (vs Byrd)
8. Andrew Golota
9. Michael Spinks (vs Tyson)
10. Victor Ortiz

Vitali had a serious injury when he was forced to retire and Spinks was knocked out cold.

The others are good examples. Cotto had to quit against Margarito because the punches he was taking were unnatural.

Ali should have quit when got his jaw broken.
