Chad Mendes will not be fighting on February 23 at UFC 157, as the promotion was unable to secure a replacement for Manny Gamburyan.

Gamburyan and Mendes were set to kick-start the pay-per-view main card from Anaheim, but Gamburyan suffered a broken thumb and fractured elbow in training recently.

In place of the bout, heavyweights Brendan Schaub and Lavar Johnson are expected to be featured on the main card.
