Former WBC middleweight titlist Julio Cesar Chavez Jnr has
apologised for his recent drugs test failure on his official
"Any attempt to explain or justify the recent developments will
be of little or no convincing, so I want to let everybody know that
I take full responsibility for my actions and the consequences
thereof," he wrote in Spanish.
Chavez tested positive for marijuana after losing his title to
Sergio Martinez last weekend.
