An injury forced Charles Oliveira to pull out of his UFC 166 bout against Jeremy Larsen and replacing him in the bout will be UFC newcomer Andre Fili. 
UFC officials announced the fight booking on Monday and the bout will be on the preliminary card.
UFC 166 takes place on October 19th from the Toyota Center in Houston, Texas and will be headlined by Cain Velasquez defending the UFC heavyweight title in his trilogy bout with former champion Junior dos Santos.
Fili (12-1) is currently on a eight fight winning streak and two of those victories came in the first round. This will be his second fight of 2013 as he defeated Adrian Diaz at WFC 5 in May.
Larsen (8-4, 1NC) entered the UFC during The Ultimate Fighter 15 and has dropped both of his fights in the UFC as a lightweight. His most recent defeat came at UFC on FX 8 as he was defeated in the third round by TKO against Lucas Martins.
