The Ultimate Fighting Championship’s fourth straight event out of the UFC Apex on Saturday in Las Vegas at least offers the best main event of the bunch, as Paulo Costa meets fellow former title challenger Marvin Vettori in a fascinating middleweight headliner. Their bout does most of the heavy lifting for UFC Fight Night 196, but there are pieces to like throughout the main card. Rising lightweight prospect Grant Dawson gets a tough veteran test in the co-feature against Ricky Glenn, and a women’s bantamweight showcase between Jessica-Rose Clark and Joselyne Edwards is well-matched and important for both competitors.
