Though Frank Mir's opponent changed for UFC 146, his sponsor didn't. He is still sponsored by the UFC, like Jon Jones. They gave him a walkout shirt that's low-key and collegiate-looking.
Plus, it has pretty stars and I'm a sucker for pretty stars. Buy it for $29.95.
Note: Junior dos Santos' walkout shirt for this weekend was not online, but you can buy this wall hanging depicting the champ, so ... win.
