Fury is one of the best fighters of his generation, reaching boxing's pinnacle as a heavyweight, but skeptics wonder whether this will stick

Have we seen the last of Tyson Fury in the boxing ring? Fury took to social media on Monday to announce he'll be retiring from boxing, less than a month after his defeat to Oleksandr Usyk in a unified heavyweight title fight in December.

The announcement comes after Fury suffered a second defeat of his career by Oleksandr Usyk last month in Saudi Arabia.
