All 22 fighters will step on the scales for the UFC 100 weigh-ins at 7PM ET on Friday, and if you can't be there in Las Vegas, you can watch the weigh-ins here at FanHouse. These weigh-ins should be particularly interesting, as UFC heavyweight champion Brock Lesnar will have to spend some time in the sauna to get down to the heavyweight limit of 265 pounds for his fight with Frank Mir, while No. 1 welterweight contender Thiago Alves sometimes has trouble getting down to 170 pounds, which he'll have to do if he wants to take champion Georges St Pierre's belt.
The video is below.
