Isaac Vallie-Flagg (born April 8, 1978) is an American mixed martial artist, who formerly competed in the Lightweight division of the Ultimate Fighting Championship. A professional competitor since 2003, he has also formerly competed in Strikeforce, Titan FC, and King of the Cage.
Vallie-Flagg is from Ann Arbor, Michigan and attended Community High School. Troubled growing up, Vallie-Flagg was not active in sports apart from dabbling with lacrosse. After viewing a UFC event, Vallie-Flagg began training in mixed martial arts and Brazilian jiu-jitsu.
Mixed martial arts career
Vallie-Flagg was scheduled to face Adriano Martins at Strikeforce: Melendez vs. Healy. However, on September 23, 2012 it was announced that the event was cancelled due to an injury to headliner Gilbert Melendez.
Ultimate Fighting Championship
Vallie-Flagg was briefly linked to a bout with Danny Castillo on April 26, 2014 at UFC 172. However, the UFC removed Vallie-Flagg from the bout in favor of a match up with Takanori Gomi. He lost the fight via unanimous decision. Despite the loss on the scorecards, Vallie-Flagg was awarded his first Fight of the Night bonus award for the bout.
Vallie-Flagg faced Matt Wiman at UFC Fight Night 57 on November 22, 2014. He lost the back-and-forth fight via unanimous decision, and was subsequently released from the promotion shortly after.
