Nate Diaz is returning to the Octagon tomorrow night for the first time in over a year, and the lightweight has encountered some difficulties while making weight for UFC on FOX 13.

The veteran fighter weighed 160.6 on his first attempt, while his opponent Rafael dos Anjos, came in at 156. Diaz has extra time to lose the additional pounds, but clearly, this is a setback in the lightweight’s return.

Not surprisingly, headliners Junior dos Santos and Stipe Miocic both made weight, as the heavyweights came in at 242 and 243 respectively.
