Is using a logo for a T-Shirt Copyrighted?

I made a really simple T-Shirt that I was going to sell. It has the Golden State Warriors' logo of the Bay Bridge on it, except the logo is black and white instead of blue and yellow. I was wondering if I am aloud to sell it. Thank you very much, for any help or knowledge at all.
Update: Also, if I don't even sell it and just wear it, is it bad/illegal?
