This is the trailer being shown by HBO to promote Martin Murray’s anticipated challenge of Sergio Martinez‘ WBC world middleweight title, set to take place at the 50,000 seater Club Atletico Velez Sarsfield in Buenos Aires, Argentina this Saturday, April 27.

The 30-year-old former British, Commonwealth and current interim WBA champion flew out to Argentina last Tuesday ahead of his challenge against one of the best P4P boxers in the world in his own backyard, in the biggest fight of his career.
