The latest in fight bookings, starring tons of heavyweights fighting in May:
-- If Roy Nelson's Facebook followers get him to drop to light heavyweight, it will have to happen after UFC 146. He will face former Strikeforce heavyweight Antonio "Bigfoot" Silva there on May 26.
-- Also at UFC 146, Cain Velasquez will take on Frank Mir in a title-eliminator bout. This is Velasquez's first fight since losing the heavyweight belt to Junior dos Santos. Mir won his last three bouts, including a gruesome submission of Antonio Rodrigo Nogueira in December.
-- During Saturday's fights, Strikeforce announced the final of the drawn-out heavyweight grand prix. With a healed hand, Daniel Cormier will take on Josh Barnett on May 19. Barnett received a conditional license from California on Monday, and the fight is expected to take place in San Jose.
-- In non-heavyweight action, Bellator lightweight champion Michael Chandler will take on UFC, Sengoku and Pride veteran Akihiro Gono at Bellator 67 on May 4 outside Toronto.
