Weidman squared off with the 38-year-old Brazilian challenger at the weigh-ins for their upcoming UFC 187 scrap in Las Vegas, and the title-holder quickly made his feelings known. The champ barked at Belfort and engaged in some aggressive banter before Joe Rogan asked him to voice his feelings.
Once the stage was his, Weidman let everyone in attendance know why he was so upset (skip to 33:15 in the following video for the altercation).
"You know, I left him alone with this whole drug test thing, but then we just found out during camp he had a 1,200 testosterone score," Weidman said.
