According to sources, Robert Guerrero caused Andre Berto to urinate blood after their fight on Saturday, which Guerrero won via unanimous decision on HBO.
Guerrero dropped Berto twice -- once in the first and once in the second -- and won by scores of 116-110 on all three cards.
It was a rough fight with Guerrero pressing the action and pushing Berto to the ropes. Guerrero concentrated on Berto's midsection, landing 74 body shots in the fight according to CompuBox.
After the bout, Berto was reportedly urinating blood. That was in addition to Berto's badly-swelled eyes, forcing him to wear shades after the bout and forego the post-fight press conference, as he was being medically tended to.
