New England Revolution star striker Kei Kamara is quite the rebel. He does what he wants and says what he wants, and he never holds back. So can you guess what happened when he needed to change his shorts during the team's match on Sunday against Chicago?

He walked off the field and changed them. And when he got back on the field, the ref gave him a yellow card for it. Here's the ref's booking with Kamara looking surprised.

Now, it seems as if the booking is for leaving the field and coming back on, which isn't allowed unless authorized by the officials, rather than the actual wardrobe switch. But it's still hilarious that a player changes in front of everyone and ends up with a yellow.
