Canelo Alvarez got on his knees to check on Amir Khan after knocking him unconscious with a big right hand in the sixth round of their title fight. Then he went over to check on some future business with fellow middleweight champion Gennady Golovkin, who was watching ringside. ”I invited him to come into the ring,” Alvarez said.
