The bout took place in the main event slot for Bellator 192 from The Forum live on Paramount Network.

Sonnen, a former UFC light heavyweight and middleweight title challenger, claimed sweeping 29-28 scores over Jackson, who previously held the UFC light heavyweight title.

Rory MacDonald finally secured a major MMA title, defeating Douglas Lima to become the new welterweight champion.

MacDonald, who was unsuccessful in his pursuit of UFC gold, scored a decision over Lima.

For MacDonald, the win was his 20th in 24 pro fights and the second straight since signing with Bellator after a run in the UFC that included wins over current UFC welterweight champion Tyron Woodley and Demian Maia.

Lima (29-7) had his second run as champion come to and in his second title defense. He had scored a decision victory last June over Lorenz Larkin.
