It’s do or die for Frank Trigg at UFC 109. If he loses to Matt Serra, it will in all likelihood be his last fight in the UFC. And unlike Serra, who has a career as a gym owner and instructor to fall back on, Trigg tells Steve Cofield he doesn’t have a plan B lined up. He’s not sure how he will make a living if he’s forced into retirement and because of that he thinks he’s hungrier than Serra to pull out the win on Feb. 6.
