There are some changes afoot for the UFC Fight Night 93 event, which takes place in Hamburg, Germany.

The UFC announced that Leandro Silva will replace Reza Madadi and now face Rustam Khabilov in a lightweight bout on Sept. 3.

The 30-year-old Silva is coming off a narrow split-decision loss against Jason Saggo at UFC Fight Night 89 in Ottawa. Before then the Brazilian had been riding a four-fight unbeaten streak, scoring wins over Charlie Brenneman, Lewis Gonzalez and Efrain Escudero. He also had a win over Drew Dober converted into a no-contest due to a referee mistake.

The 29-year-old Sambo champion Khabilov has won back-to-back fights, his latest coming against Chris Wade at the UFC's event in Rotterdam in May. Since debuting successfully in the UFC in late 2012 against Vinc Pichel, Khabilov has gone 5-2 in the Octagon, with wins over Yancy Medeiros and Jorge Masvidal.

UFC Fight Night 93 takes place at the Barclaycard Arena in Hamburg, and will feature a heavyweight bout in the main event between Josh Barnett and Andrei Arlovski, as well as a light heavyweight clash between former contender Alexander Gustafsson and Jan Blachowicz.
