MLB permanently retired the #42 in 1997. However, they allowed anyone who was wearing #42 at the time to continue to wear it. Mariano Rivera of the Yankees is the only player wearing #42 currently as he was in MLB at the time of its retirement. Once he retires, no one will ever again wear the #42 in MLB.
