Mexican boxer Erik Morales has been banned from the sport for two years after testing positive for a banned substance.
The United States Anti-Doping Agency revealed on Friday that the 36-year-old had tested positive for the prohibited anabolic agent Clenbuterol in October 2012.
'El Terrible' has won world titles at four different weights, with his most famous win coming against Manny Pacquaio in 2005.
He has most recently been involved in two fights with Danny Garcia, both of which he lost.
