Plus, a Welterweight championship eliminator, a Flyweight championship eliminator, and an up-and-coming Lightweight takes on a veteran division guardian with a pension for intense, violent action. It’s Silva vs. Diaz! It’s Gastellum vs. Woodley! It’s Lauzon vs. Iaquinta! It’s Lineker vs. McCall! It’s Head vs. Heart!
