The weigh-in for tomorrow's lightweight fight in London between Michael Katsidis and Ricky Burns, with super middleweights George Groves and Paul Smith squaring off in the featured undercard bout, will stream live at 10 a.m. EDT. You can access the video below right here at Bad Left Hook.

Katsidis (28-4, 23 KO) is returning to lightweight after a one-off bout at 140 pounds in August against Michael Lozada in Australia. It was a homecoming showcase for the Aussie, who hadn't fought in his native country since 2006. After that final bout at home, Katsidis headed to the United Kingdom for the first time in 2007, defeating Graham Earl in a Fight of the Year contender, so it's only fitting that he returns to the scene in London this time out, too. Katsidis also thrashed Kevin Mitchell in West Ham in May 2010, so he's 2-0 in England.

Burns (32-2, 9 KO) is coming up in weight from 130 pounds. He's had some fights at lightweight and higher in the past, but this is the first time he's taken a serious crack above the super featherweight division.

Groves (13-0, 10 KO) is fighting for the first time under Frank Warren's banner, defending the British super middleweight title he won on May 21 by defeating longtime rival James DeGale. Smith (31-2, 17 KO) is a credible challenger and a former British champion himself.
