Following his weekly address, the first Argentine pope met Martinez
in St. Peter's Square.
The two shook hands and spoke briefly, though
there is no record of what either man said.
Martinez presented the pope
with a WBC world championship belt.
Martinez is known as one of boxing's good guys who works tirelessly
to aid charities.
One of his key initiatives is an anti-bullying
initiative.
Martinez is injured and not expected to fight again until next year.
