The UFC on FOX 5 weigh-in’s took place on Friday afternoon in Seattle and Nate Diaz would need additional time to make weight for his fight tomorrow night against Benson Henderson. 
In title fights, there is no one pound allowance and he initially weighed in at 155.6 pounds.
After taking the additional time allowed by the commission, Diaz made weight at 155 pounds and his fight with Henderson became official after the champion already made weight.
