UFC Vegas 23 weigh-in results The UFC Vegas on 23 (aka UFC on ABC 2) main event pits fast-rising middleweight contender Marvin Vettori against late-replacement Kevin Holland. No. 6 ranked Vettori was originally slated to meet no. 5 ranked Darren Till, but Till had to withdraw because of a broken collarbone. Anxious to get the fight in, Vettori was first to the scale, weighing 186 pounds, the upper limit for a middleweight non-title bout. Holland followed a short time later, stepping on the scale at just 183.5 pounds. Vettori is on a four-fight winning streak. His last loss was to current champion Israel Adesanya. Vettori lost that bout via a split decision well before Adesanya claimed the UFC middleweight title.
