The Brazilian light heavyweight prospect quickly became a fan favorite in the UFC after knocking out Khalil Rountree and Justin Ledet in a combined time of two minutes and 12 seconds. Days after his recent win, Walker went on social media to call for a top 15 opponent.
Cirkunov was matched-up against Ovince Saint Preux at UFC 235, which takes place Saturday in Las Vegas, but was left without an opponent on Feb. 9. Walker wasted no time, offering to replace “OSP” against Cirkunov, and got the fight 48 hours later.
