The MMA injury bug rolls on unabated and this time claims a preliminary card bout for the final UFC show of 2012. UFC lightweight Cody McKenzie is out of his bout with Leonard Garcia at UFC 155. Max Holloway has agreed to replace McKenzie for the contest, the UFC announced on their website.

"With Cody McKenzie injured, Leonard Garcia gets a new opponent in Max Holloway," the statement read. "Verbal agreements are in for that bout as well." The nature of McKenzie's injury was not directly specified.

Holloway, 21, most recently fought at UFC 150 in August of this year, besting Justin Lawrence by TKO in the second round. He is 2-1 in the UFC and 6-1 in professional MMA.

Garcia, 33, is on a three-fight losing skid. He's dropped three consecutive fights to Chan Sung Jung, Nam Phan and most recently Matt Grice at UFC on FX 3 in June of 2012. He is 6-8-1 in UFC competition and 15-9-1 in professional MMA overall.

UFC 155 takes place on December 29th at the MGM Grand Garden Arena in Las Vegas, Nev., and is headlined by a heavyweight title fight between champion Junior dos Santos and challenger Cain Velasquez.
