They didn't look intentional which is probably why Calvancante wasn't DQed. JZ hit him with about three elbows while Aoki shot in on him. The first elbow hit Aoki in the back/rib, the second hit him in the upper back/neck area and the third looked like it was going in the same direction but Aoki crumpled to the mat before it hit completely.
I think I read that Aoki wanted to continue but his corner and the ringside doctor advised against it, so the fight was called off.
I found the fight
here.
