Chimaev misses weight
Khamzat Chimaev misses weight by 7.5 pounds
The nontitle welterweight limit is 171 pounds and Chimaev weighed in at 178.5 pounds. Diaz was 171 pounds.
Chimaev, 28, is one of the UFC's biggest rising stars and was a -1000 favorite, per Caesars Sportsbook.
When Chimaev weighed in Friday morning, he shrugged his shoulders and showed no contrition for the massive miss. Later, he posted a meme joking about missing weight on Twitter.
