A lightweight contest between Joe Lauzon and Jim Miller has taken the place of Phil Davis-Forrest Griffin in the co-main event slot for UFC 155.

The card takes place December 29 from Las Vegas. The headliner fight is Junior dos Santos-Cain Velasquez for the UFC heavyweight title.

Griffin was forced out of the planned match with Davis after suffering a knee injury in training. No replacement for Griffin was found, knocking Davis off the card, as well.

To fill the extra main card slot, Chris Leben and Karlos Vemola have been moved off the prelims and will now open the pay-per-view main card.
