Kattar and Allen both successfully made weight on Friday ahead of their main event of UFC Vegas 63, which takes place at the UFC APEX and streams on ESPN+.
“The Boston Finisher” was first to the scale and hit the limit at 146 pounds. Allen, who will look to improve to 10-0 in the UFC, was right behind him and made the matchup official by weighing in at 145.5 pounds.
While 21 of the 22 fighters were on the mark, the card’s opening bout became a catchweight. Newcomer Joshua Weems, taking the fight on short notice to replace Garrett Armfield, weighed in at 139.5 for his bantamweight fight with Christian Rodriguez — who was the last fighter on the scale. Rodriguez was good to go at 136 pounds. The fight will proceed with Weems forfeiting 30 percent of his purse to Rodriguez.
