For the second fight in a row, Melvin Guillard has failed to make weight, and as a result, the veteran will no longer challenge Justin Gaethje for the WSOF lightweight title tomorrow night.

Guillard came in at 158.8 on his first attempt this afternoon in Tampa, Florida, and on his second try, the fighter weighed 158.6 according to a report from MMA Fighting.com). As a result, his bout with Gaethje has been changed to a 159 pound, non-title catchweight fight. Guillard reportedly will also be hit with a fine that’s 50% of his purse.

Here are the weigh-in results for WSOF 15, which will feature middleweight champ David Branch taking on Yushin Okami, and strawweight champion Jessica Aguilar taking on Kalindra Faria.

The event will be hosted by the USF Sun Dome and the main card will be broadcast on the NBC Sports Network.
