Anthony Smith missed weight by four pounds despite being on call for UFC 283 as a replacement fighter for the main event.
Smith, 34, was weighing in the event that Glover Teixeira or Jamahal Hill were forced to pull out of the vacant light-heavyweight title fight. Replacement fighters have been implemented by the UFC in recent years because of high-profile fights being cancelled on short notice, due to tough weight cuts or other medical issues.
Texeira and Hill both successfully made weight the 205lb limit for their title clash but Smith failed to come in at the light-heavyweight limit as he stepped on the scale at 209lb. If Smith is unable to lose the additional four pounds in the two-hour window, he will be ineligible to win the light-heavyweight title if he is called upon to replace Teixeira or Hill in the main event.
