An undisclosed injury has forced Tarec Saddiedine to pull out of his UFC on FOX 8 bout against Robbie Lawler and he will now face Siyar Bahadurzada. 
UFC officials announced the fight booking on Tuesday and the fight is expected to take place on the main card on FOX.
UFC on FOX 8 takes place on July 27th from KeyArena in Seattle and will be headlined by Demetrious Johnson defending the UFC flyweight title against John Moraga.
Lawler (20-9, 1NC) recently made his return to the UFC in February and won the knockout of the night bonus at UFC 157 when he defeated Josh Koscheck. It was his first fight in the UFC since 2004 and it was his return to the welterweight division.
Bahadurzada (21-5-1) entered the UFC last year and won his debut at UFC on FUEL TV 2 against Paulo Thiago by knockout. After being out for nearly a year, he returned in March at UFC on FUEL TV 8 and was defeated by Dong Hyun Kim by unanimous decision.
