VIDEO : Retired Boxer Floyd Mayweather's Long History Of Coming Out Of Retirement

According to a report by Business Insider, if retired boxer Floyd Mayweather ever chooses to return to the world of boxing for one final cash grab it may not go the way the undefeated may think. The 41-year-old first retired in 2007, then again in 2009, and then finally again in 2015. While boxing fans and critics thought, and perhaps hoped, that would be the end, however Mayweather came out of retirement again in 2017 for his fight with MMA star Conor McGregor.
