NBC reports DC Comics has applied some kryptonite of their own to the NBA's plans to produce Nate Robinson "Krypto-Nate" t-shirts.

The NBA planned to start selling green Knicks t-shirts with Nate Robinson's number four. Instead of Robinson over the four on the back, though, they were going to write Krypto-Nate to commemorate his dunk over "Superman" Dwight Howard. DC Comics, which publishes Superman comics, objected to the idea/wanted their share of the profits, however, and the shirts were sent to the Fortress of Solitude for the time being.

Instead, the NBA and DC are trying to come up with a way to join forces in a Justice League of their own.

"The NBA decided not to release the Krypto-Nate T-shirt because of future initiatives we are working on with Warner/DC Comics," an NBA source told The New York Post.
