The two will square off in the main event on October 20 from Uncasville, Connecticut and the Mohegan Sun Arena.

Mousasi (42-6-2) signed with Bellator after a run in the UFC, reuniting with Scott Coker from their days together in Strikeforce. Shlemenko (56-9) is a former Bellator champion who has gone 12-3 with the promotion.

Also, former Bellator champion Liam McGeary takes on Muhammed “King Mo” Lawal in a featured clash that same evening.
