Mosley announced his second retirement on December 7, 2013. He stated that he plans to become a trainer, to train his son, Shane Jr., and other young fighters. In an interview with World Boxing News, when asked if he had any desire to lace up his gloves and return to the ring professionally, he said he would only consider a return to the sport against the very top welterweights in the world. He specifically named Floyd Mayweather Jr., Manny Pacquiao, and Juan Manuel Márquez. He also said in another interview in early 2015 that he was not sure if he would fight again, but that he wanted to come back and face a fighter of similar age and specifically named Juan Manuel Márquez.
