Ian McCall is currently the 3rd ranked flyweight in the Ultimate Fighting Championship. In the first ever flyweight bout of UFC history McCall competed to a majority draw with the current UFC Flyweight Champion Demetrious Johnson. This was in the semifinals of the UFC Flyweight Tournament in a bout that took "Fight of the Night" honors. They later had a rematch to see who would advance to the final of the UFC Flyweight Tournament that saw Ian narrowly beaten to a decision by Demetrious.
