Sergio Martinez vs Martin Murray: Fight time, live stream, results, round-by-round coverage, TV schedule

Tonight on HBO, Sergio Martinez returns to defend his middleweight crown against Martin Murray. It's the first-ever trip to Argentina for HBO, and Jim Lampley, Max Kellerman, and Roy Jones Jr will have the call ringside, with Harold Lederman in his familiar role as unofficial scorer.

Here's how you can watch:

Fight Time: 8:30 pm EDT

TV: HBO (US) / BoxNation (UK) / TV Publica (Argentina) / TyC Sports (Argentina)

Venue: Velez Sarsfield - Buenos Aires, Argentina

Undercard: Luis Carlos Abregu will face Antonin Decarie in a 12-round welterweight bout, which will be televised ... Former European super bantamweight champ Kiko Martinez returns to take on Damian David Marchiano ... IBF female featherweight champ Dahiana Santana takes on Claudia Andrea Lopez.

Martinez (50-2-2, 28 KO) is the overwhelming favorite in the fight, but Murray (25-0-1, 11 KO) is a determined, unbeaten fighter whose only non-win was a debated draw against Felix Sturm in 2011.
