WWE.com is now acknowledging the change to the Smackdown Elimination Chamber match this Sunday for the WWE World Heavyweight Championship with Santino Marella replacing Randy Orton. Orton has been pulled from the match due to a concussion (believed to be legitimate). The updated lineup features Daniel Bryan defending against Big Show, The Great Khali, Wade Barrett, WWE Intercontinental Champion Cody Rhodes and Santino Marella.
