An injection has forced Erik Perez to pull out of his fight on Saturday night at UFC 159 against Johnny Bedford and Bryan Caraway will step in to replace Perez. 
UFC officials announced the change on Monday and the fight between Bedford and Caraway will take place on the preliminary card on FX.
UFC 159 takes place on Saturday from the Prudential Center in Newark, New Jersey and will be headlined by Jon Jones defending the UFC light heavyweight title against Chael Sonnen.
Caraway (17-6) won his first two fights in the UFC after being on The Ultimate Fighter 14 and is coming off a lost at UFC on FUEL TV 8 against Takeya Mizugaki. He lost the fight by split decision and it was his first lost since 2010, which came in the WEC against Fredson Paixao.
