For anyone who wants to watch the fight tomorrow online, here's a copy of an e-mail I received from BoxNation which contains a link to the official stream. I've heard the picture and sound quality will be top notch!

Our line up this weekend includes Nathan Cleverly v Tony Bellow for the WBO Light – Heavyweight Championship on Saturday from 18:00 (UK Time).

Please note whilst the e-mail suggests the action starts from 6pm, I have been reliably informed the broadcast will be from 7pm. I do not know if this link will also cover Bernard Hopkins Vs. Chad Dawson at 2am Sunday morning.
I'll keep you posted if I get further info.
