“My opponent caught me with a good downstroke. I'm done with boxing, this is the end for me, unfortunately. It's time for me to spend more time with my family,” said Collazo, who recently became a grandfather.
Collazo has victories over such names as Miguel Angel Gonzalez (TKO 7) and Victor Ortiz (KO 2) and losses to Ricky Hatton, Shane Moseley, Andre Berto and Keith Thurman.
