Michael Phelps , following his arrest last week for a DUI, USA Swimming announced Monday that they're suspending the Olympic star for six months. As a result, he won't be able to compete until April 6th, 2015. The organization is also halting his funding for six months and he'll have to withdraw from the 2015 world championship team, so Phelps won't be in the water next August in Kazan, Russia, which is considered an important step for the 2016 Olympics in Rio de Janeiro.
