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.

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

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