UFC officials announced the injury today. They also announced that former Cage Rage champion Jason Young will replace Yahya in the bout.
Poirier defeated Josh Grispi at UFC 125 in January in a bout where he was a significant underdog. It was his debut fight at 145 pounds after competing as a lightweight for the majority of his career. Poirier is also the focus of Fightville, a new documentary from Michael Tucker that was purchased by Showtime over the weekend.
Young sports an 8-3 record and is known as a stellar kickboxer.
