UFC Swing Bout (???)
Carlos Newton 175 lbs
Renato Verissimo 174 lbs
Just to clarify something. The swing bout between Carlos Newton and Renato Verissimo was originally scheduled as a Welterweight Bout, but it is believed that Carlos Newton had flight problems arriving late from Canada, therefore he didn’t have adequate time to cut the last bit of weight to make 170 lbs, so the Nevada State Athtletic Commission talked to both fighters about the situation. Both fighters agreed a new weight limit with the Commission for 175 lbs, which both fighters made. Although, technically it is inside the Middleweight pool, the maximum weight was scheduled for 175 lbs rather than 185 lbs, therefore it is not yet known what division it will be classed in officially.
