Originally scheduled to face Bobby Green on June 9, Clay Guida will now take on Brazilian jiu-jitsu expert Charles Oliveira, who stepped up to replace Green on 10 days’ notice. The UFC announced the match-up on Wednesday.
According to sources, Oliveira still needs to get a work visa and medical exams done before flying to Chicago next week.
Guida (34-17) last fought in November, putting a swift end to Joe Lauzon in 67 seconds.
Oliveira (22-8, 1 no-contest) is 1-1 since he was forced to move back up to the lightweight division, recently losing via second-round TKO to Paul Felder.
UFC 225 will be headlined by a pair of championship bouts at the United Center. Robert Whittaker will defend his middleweight belt against Yoel Romero in the main event, while Rafael dos Anjos and Colby Covington face off for the interim welterweight title in the co-main event.
