Two fighters have been forced off the year-end UFC 155 card, as Karlos Vemola and Cody McKenzie have suffered injuries.
Chris Leben, who was set to face Vemola, will now meet Derek Brunson, according to MMAjunkie.com. The two will still kick-start the pay-per-view on December 29 from Las Vegas.
Also, the UFC is searching for a replacement for McKenzie, who was expected to meet Leonard Garcia on the prelims.
Brunson will be making his UFC debut after fighting in Strikeforce. He is 9-2, with seven career first round stoppage victories.
