Though MMA's spring schedule is not as dizzying as its winter pace, there are plenty of fight cards that need filling. To that end:
-- Jason "Mayhem" Miller will take on C.B. Dollaway at UFC 146 on Memorial Day weekend in Las Vegas. This is Miller's first fight since losing the Michael Bisping at "The Ultimate Fighter" season 14 finale. Dollaway has been finished in his last two bouts, a TKO to Jared Hamman and a KO to Mark Munoz.
-- Evan Dunham and Edson Barboza will also meet at UFC 146. Dunham just fought at UFC on Fox 2, scoring a win over Nik Lentz. Known for his powerful striking, Barboza has never lost. His knockout of Terry Etim at UFC 142 was called one of the best knockouts in UFC history.
-- In Bellator, Eddie Alvarez and Shinya Aoki are expected to meet in April. Alvarez was submitted by an Aoki heel hook in 2008. After that loss, he won seven straight before losing a classic title bout to Michael Chandler. Aoki is currently holds the DREAM lightweight belt.
