Iaquinta won the first outing by way of unanimous decision at UFC 169 in 2014. Since then, both fighters have earned the opportunity to fight for the UFC lightweight title.
Since their fight four years ago, Lee has fought 12 times for the UFC, picking up 10 wins and just two losses in that time. Iaquinta, a little less active, has fought seven times since the 2014 bout, also losing two.
