Mike Tyson was one of the most feared and formidable boxers of his generation and came to define the heavyweight division during the 1990s. The youngest fighter to win the heavyweight world title, Tyson's career was one of incredible highs and chaotic lows, both in and out of the ring. Even now, 15 years after his retirement, Tyson still attracts a huge amount of interest from boxing fans and media alike. The 53-year-old American has millions of social media followers and has launched a very successful podcast. It was to those millions of followers that Tyson published some video highlights on his Instagram account of him looking as ferocious as prime 'Iron Mike', bobbing, weaving, and pounding the pads with his famously powerful hooks and uppercuts. Teasing the viewers with a potential comeback, Tyson turns to the camera and says: "I'm back." There have been reports in recent days suggesting Tyson - who built a professional record of 50 wins and six defeats - could take part in an exhibition contest against old foe Evander Holyfield, while New Zealand rugby star Sonny Bill Williams, who once held the New Zealand heavyweight championship, has also been suggested as a possible opponent. Whomever Tyson faces should he return to the ring, they look set for a rough ride based on the former undisputed champion's power in the video above.
