UFC on Fox: Lee vs. Iaquinta 2

UFC on Fox: Lee vs. Iaquinta 2 (also known as UFC on Fox 31) is an upcoming mixed martial arts event produced by the Ultimate Fighting Championship that will be held on December 15, 2018 at Fiserv Forum in Milwaukee, Wisconsin, United States.

Background
After previously contesting two events (UFC Live: Hardy vs. Lytle and UFC 164) in Milwaukee at Bradley Center, the event will be the first for the promotion at the newly-built venue.

The event will also mark the end of the UFC's seven years with Fox as a new broadcast deal with ESPN is slated to begin in January 2019.

A lightweight rematch between former interim title challenger Kevin Lee and Al Iaquinta is expected to serve as the event headliner. The pairing met previously in February 2014 at UFC 169 with Iaquinta winning the fight via unanimous decision.

Erik Koch was expected to face promotional newcomer Dwight Grant in a welterweight bout. However, Koch was removed from the card on November 28 for undisclosed reasons and replaced by Zak Ottow.
