At UFC 131, Shane Carwin showed a ton of heart in his fight with Junior dos Santos.
Carwin fought his way through a rough first round, much like his opponent at UFC 116, Brock Lesnar.
Although Carwin did not pick up the win, he showed why he is one of the toughest MMA fighters today.
Despite being 36, Carwin still has some fight left in him. Here are three fights he should take to send him back in the right direction.
