An undisclosed injury has forced Bruno Santos to pull out of his UFC 175 fight against Chris Camozzi and replacing Santos in the fight will be Trevor Smith. 
The fight change was announced by the UFC on Thursday.
UFC 175 will come from the Mandalay Bay Events Center in Las Vegas on July 5th and is scheduled to be headlined by Chris Weidman defending the UFC middleweight title against former light heavyweight champion Lyoto Machida.
Smith (11-5) has dropped four of his last six fights and has gone 1-1 in the UFC. After winning his UFC debut earlier this year, he returned in January at UFC Fight Night 39 and was defeated by Thales Leites.
Camozzi (19-7) was scheduled to fight Andrew Craig at UFC Fight Night 39 in April, but Craig was pulled from the fight on weigh-in day when he came down with an illness. Camozzi will be looking to snap a two fight losing streak in this fight as his last win came at UFC 158 last year against Nick Ring.
