vipboxonline.eu
or
boxingguru.tv (usually has better options)
Both of those will have plenty of links, just gotta sort through and find the best quality one.
For a free link of the fight. Go to Youtube.com and type in Bradley for Marquez full fight. They will have a video that's 12:44. The quality of the picture is poor and the volume is very low. But, it sums the full fight into a 12 minute span.
I always just go on twitter and search "boxers names + live stream" and usually theres a bunch of tweets posting good links. I'm going out to 1st and 10 and watching it.
you can purchase a 1 day subscription at HQzones.tv for only $5. It's the best value-to-picture quality deal you'll likely find.
