Cubs' Carl Edwards Jr. Showcases 'Carl's Jr.' Jersey

(CBS) This weekend is Players Weekend across MLB, in which uniform policies are relaxed so that players' personalities are allowed to be showcased more.

As part of that, players will wear nicknames on the back of their uniforms. On Friday ahead of a series opener at Philadelphia, Cubs reliever Car Edwards Jr. tweeted a photo of his uniform -- with "Carl's Jr." on the back as one of the funnier nicknames across baseball.
