Jackson earned a decision victory over Muhammed "King Mo" Lawal in the main event, earning the Season 10 light heavyweight tournament title. He will face champion Emanuel Newton for the belt next, but asked for a rematch with Lawal after the fight.
"I'm not happy with my victory," said Jackson, who improved to 3-0 with Bellator. "I want a rematch. Let's come back and do it at the FedEx Forum (in Memphis)."
Lawal was stunned by the loss, saying, "You know I won that fight." He made several comments to Bellator CEO Bjorn Rebney inside the cage after.
In the co-main event, Will Brooks pulled an upset, winning the interim lightweight title with a split decision victory over Michael Chandler. Brooks, a former tournament winner, agreed to meet Chandler after Eddie Alvarez was knocked out of the planned main event with a head injury.
Ortiz, making his Bellator debut, overwhelmed an under-sized Alexander Shlemenko, securing a takedown and locking up a submission just moments into their fight. Shlemenko is the current middleweight champion, but agreed to the fight at 205 pounds.
"Guess who's back," shouted Ortiz after the win, before going into an impersonation of a Hulk Hogan victory speech."
In earlier main card action, Alexander Volkov earned a future heavyweight title fight after submitting Blagoy Ivanov, while Michael Page earned a first round knockout when he finished Ricky Rainey.
