Here’s what happens when you put UFC Fighters in a Polar Vortex in Chicago! Yesterday was our first day to Chicago for UFC on Fox: Henderson vs Thomson and DAMN it’s friggin’ cold!! Apparently it is the second coming of a phenomenon called a Polar Vortex and we happen to be here in the middle of it! Sub zero temperatures didn’t keep us from heading outside though! Check out what some of the fighters went to do!
