Wearing jeans, B.J. Penn (16-7-1) weighed-in at 167.2 pounds during Saturday's official UFC 127 weigh-in at Acer Arena. Jon Fitch (23-3) came in at 169.8 pounds. Both were under the welterweight limit of 171 pounds.
Jorge Rivera has fought some of the UFC's biggest names, but it took an out-of-character moment of antagonism to get Michael Bisping -- and fight fans -- to give the veteran middleweight their undivided attention.
The UFC welterweight division will have its next No. 1 contender by the end of the month. A future title shot will be on the line Feb. 27 when B.J. Penn faces Jon Fitch in the main event of UFC 127 in Sydney.
