Justin Ledet has a new opponent for Saturday’s UFC Fight Night event in Pittsburgh.

The undefeated heavyweight was matched up against Dmitry Sonsvskiy, but Azunna Anyanwuhas stepped in on short notice to replaced the injured fighter on Sept. 16. The UFC announced the change Monday.

Ledet (8-0, 1 no-contest) hasn’t fought since Nov. 2016, and returns to action after accepting a four-month USADA suspension. The 28-year-old fighter is 2-0 under the UFC banner with wins over Chase Sherman and Mark Godbeer.

Anyanwu (14-4) signed with the UFC after finishing Greg Rebello in the first edition of Dana White’s Tuesday Night Contender Series in July, and enters the bout riding a five-fight winning streak.

UFC Fight Night 116 takes place at the PPG Paints Arena in Pittsburgh, Penn., and features Luke Rockhold vs. David Branch in the main event.
