Reza Madadi (13-3 MMA, 2-1 UFC) has been forced out of his lightweight fight against Michael Chiesa (9-0 MMA, 2-0 UFC) at UFC on FOX 8, and Jorge Masvidal (24-7 MMA, 1-0 UFC) will step in to take his place.

The announcement was made on Tuesday night’s edition of “UFC Tonight” on FUEL TV. Visa issues for Madadi reportedly are to blame.

UFC on FOX 8 takes place July 27 at KeyArena in Seattle and is headlined by a flyweight title fight between champion Demetrious Johnson and top contender John Moraga. The main card airs on FOX following prelims on FX and Facebook.

Masvidal in April won his UFC debut with a unanimous decision victory over Tim Means after coming over from Strikeforce, where he went 6-1 with the lone loss coming in a lightweight title fight against champion Gilbert Melendez. The American Top Team product also has fights for Bellator and Sengoku on his resume.

Chiesa won Season 15 of “The Ultimate Fighter,” upsetting favorite Al Iaquinta and winning “Submission of the Night” at the show’s live finale. In February, he picked up a rear-naked choke win over Anton Kuivanen at UFC 157.

Meanwhile, Madadi, a resident of Sweden, was going to be fighting for the first time in the United States. “Mad Dog” competed in both of the UFC’s visits to Sweden, picking up a win over Michael Johnson this past month and a submission win over Yoislandy Izquierdo in 2012. In the middle, he dropped a split decision at UFC 153 to Cristiano Marcello.

With the change, UFC on FOX 8 now includes:

MAIN CARD (FOX, 8 p.m. ET)

Demetrious Johnson vs. John Moraga – for UFC flyweight title Jake Ellenberger vs. Rory MacDonald Robbie Lawler vs. Tarec Saffiedine Liz Carmouche vs. Miesha Tate

PRELIMINARY CARD (FX and Facebook, 4 p.m. ET)
