The UFC’s final fight card of the year is a deep one. On top of a loaded pay-per-view main card at The Forum in Inglewood, Calif., the promotion has put together a preliminary-card lineup that includes two former champions, a former title challenger and more.

Former UFC heavyweight champion Andrei Arlovski (27-17 MMA, 16-11 UFC) participates in the featured bout. “The Pitbull” will set a new record for most heavyweight appearances inside the octagon when he takes on Walt Harris (11-7 MMA, 4-6 UFC) in a fight that hopes to keep the winner relevant in the weight class.

The UFC 232 prelims have more to offer than that, though. Check out all the numbers behind the eight-fight lineup that will lead into the main card as the promotion closes out 2018.
