Momentum shifted in the boxing world seven years ago when Andy Ruiz Jr. pulled off a stunning upset against Anthony Joshua, winning the heavyweight title with a devastating knockout. The 29-year-old Mexican boxer's victory was met with widespread shock and amazement, with many experts predicting a long and grueling road to recovery for the defeated champion. Ruiz Jr. went on to successfully defend his title twice, but ultimately lost it to Joshua in a rematch. Now, at the age of 36, Ruiz Jr. is looking to revive his career with the help of his old trainer, Jorge Diaz.

Consequences of Ruiz Jr.'s potential comeback are being closely watched by investors and boxing fans alike. A successful resurgence could lead to a significant increase in boxing's popularity, with potential new revenue streams from pay-per-view events and sponsorships. On the other hand, a failure could lead to a decline in the sport's overall viewership and revenue. As the boxing world waits with bated breath to see what the future holds for Ruiz Jr., one thing is clear: the stakes are high.

Industry insiders point to the 1990s as a key period in the evolution of boxing, when fighters like Mike Tyson and Evander Holyfield dominated the sport. Since then, the sport has experienced a decline in popularity, with many citing the rise of mixed martial arts (MMA) as a major factor. However, with the resurgence of interest in traditional combat sports, Ruiz Jr.'s comeback could be a much-needed shot in the arm for the sport. According to a recent survey, 40% of Americans believe that boxing is experiencing a resurgence in popularity.

Risks and opportunities abound as Ruiz Jr. prepares to step back into the ring. A potential rematch against Joshua could be a major catalyst for the sport, with many experts predicting a blockbuster event that could draw in millions of viewers worldwide. On the other hand, a loss could be a major setback for Ruiz Jr. and the sport as a whole. As the big question on everyone's lips is: can Andy Ruiz Jr. do it again, one thing is certain: the boxing world will be watching with great interest.
