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.
