Missing weight is a cardinal sin in the UFC and both Kelvin Gastelum, twice, and John Lineker, four times, are the worst offenders. DFW told reporters today that Gastelum will not fight at welterweight again and will be moved up to middleweight, and likewise Lineker will be moved up to bantamweight, both out of concern for their health. Perhaps seeing Anthony Johnson have success at his natural weight class will help the transition?
Gastelum at middleweight will be interesting, he is pretty short and stocky. Maybe he can be the Cormier of the middleweight division.
Neither of these guys want to move up. I'd be surprised if they take more than one fight each before trying to get back down again.
