Brock Lesnar and Shane Carwin both registered at the 265-pound limit for their heavyweight championship bout.
Complete weigh-in results after the jump.
As of last week there is no longer an argument for Fedor Emelianenko being the No. 1 heavyweight in the world, and Carwin acknowledged after the weigh-ins the additional prestige the bout carries.
"Tomorrow we find out who the baddest man in the planet is," said Carwin, who captured the interim title bout in March with a first-round TKO over Frank Mir.
Lesnar, who is fighting in his second straight unification bout, is returning after missing nearly a year of action due to a serious case of diverticulitis.
"I'm just excited to get back in the Octagon, it's been a long road," Lesnar said. "That's all I have to say. I'm ready to fight."
