In the first quick fight of WEC 40, Rani Yahya won quickly with a rear naked choke over former bantamweight champion, Eddie Wineland. Yahya came out aggressive at the start, quickly taking Wineland's back. Wineland worked up to his base, but couldn't shake Yahya, tapping to end the fight early in the first round.
Wineland is from northwest Indiana, and as a fighter at Miguel Torres' gym, he had a large contingent of fans at the UIC Pavilion. They were not happy about his loss, and this was the second loss that got the crowd booing. Tapia's close decision loss also brought out the boo birds.
